+
+Ahhh what a wonderful few days in Barcelona. Yesterday when we went to bed, it started raining. Then
+at 02:00 or so, we both got abruptly woken up by a thunderclap just overhead. There was a bright
+flash of white and a very loud and immediate thunder. Wowza! I fell alseep pretty quickly after the
+excitement, but Marina spent a bit longer before being able to fall asleep. Stupid weather!
+
+This morning it's still raining, so we decide to take our breakfast in the hotel. It's a nice
+spread, Marina takes an _Americano_ and I take a _Mediterraneo_, and all sorts of yummy food is
+presented. We take our time eating it, as our checkout is only at noon, and we are not super keen on
+walking through the rain to the metro and then the airport.
+
+Marina sees an Aeronautical museum at the airport, but unfortunately it's open only until 13:00 on
+Saturdays. Not to worry, I have not seen much of the city on this particular trip, so I offer
+perhaps to go check out this little Gaudi wall a few blocks up from us. We find the wall and the
+statue of _Antoni Pl&agrave;cid Guillem Gaud&iacute; i Cornet_, as his full name rings. From here,
+we take our time walking through a light drizzle and decide to take a look at the museum for
+forbidden art - these are all artworks that were displayed at some point, but due to pressure,
+typically from old, straight, white, christian dudes, were demanded to be removed. I find some of it
+curious, other pieces are a bit pushy, and overall I think that old straight white christian dudes
+should just chill out more.
+
+After this small (but in my opinion, very cool) museum, it's still raining. So we walk over to a
+small cafe and have a cup of cappucino and share a red velvet cupcake. My body is sluggish and slow.
+My favorite activity would be curling into a ball and sleeping some more right now, so Marina goes
+easy on me. We slowly walk East to the _Arc de Triomf_ and from there through the promenade and into
+the park and towards the Equestrian statue of General _Joan Prim_.
+
+We have a drink at a small greek bar/restaurant, and from there it's pretty close to catch the metro
+at _Barceloneta_. We decide to minimze the rainy walk and take the metro L4 up to _Verdaguer_,
+where we descend like twelve escalators (not even kidding!) to catch the L5 metro to _Collblanc_ and
+from there it's easy: just jump onto the L9S directly to the airport. And all of this for a EUR 5.50
+train ticket. The public transport in this city is **excellent**!
+
+We are at the airport at about 17:30 for a 18:45 planeride. That means we should probably have some
+dinner before boarding. Marina insists that we eat Tapas, and since our buddy Ram&oacute;n had
+previously suggested we drink a wine from Priorat, we oblige. "One of everything!", is the order,
+and soon after there are seven dishes on our table.
+
+The food is really good - not just by "airport"-standards, but just in general: great preparation,
+nice and moist _tortilla_, crispy braised _padrones_, thinly sliced _jamon_, and six units of
+_croquetta_. We also enjoy the Priorat red wine and report back to the _Hardship Brotherhood_ on our
+progress.
+
+We finish our dinner and hop-skip to the gate, where the boarding has already started. We get into
+the plane, there is a bit of a kerfuffle on airplane seats - our assigned seat does not exist
+because they changed the aircraft. We are not alone, and one set of people even got assigned _the
+same_ seat. Hilarity ensued but in the end, everybody managed to sit.  Our flight home is
+_tranquillo_, and we land at Zurich airport at about 21:20, and are home at about 22:00 or so.
+
+We catch up with Quinn who has enjoyed the time 'off of parents', probably more so than I enjoyed
+the time 'off of son', and we open up the gazillion packages in the mail. Marina went to town on
+Aliexpress it seems. I also may have ordered a package or two :)

+
+I woke up at 08:30 after a tremendous sleep. I love sleeping in my own bed, the difference between
+its comfort is most apparent just after I return from a trip abroad. This morning I have a sportsing
+date with Johhny and Mari. A while ago, maybe half a year by now, Johnny mentioned that he's into
+[[Padel](https://en.wikipedia.org/wiki/Padel)], a racket sport of Mexican origin, typically played
+in doubles on an enclosed court slightly smaller than a doubles tennis court. 
+
+It feels fitting to play this game precisely today, as I understand it's the second most popular
+game in Spain, second only to football. Seeing as I just got back from Spain, I may as well :) I
+drive over to _Milandia_ and enter the Padel hall to find a jolly Mari and Johnny already there. I
+have never played this game before, but I have played both tennis and squash, so I think I will get
+the jist of it 🎾. Mari and I have to go rent a racket, and it becomes apparent that Johnny hasn't
+played particularly often with his: the price tag is still on his racket :)
+
+It's a super fun game! We are only three, so we take turns ganging up on a singleton. The trick
+seems to be moderating power. It's very easy to whack the ball against the back wall (it has to
+bounce on the court first), or thwack it out of the court, and onto the next team's court. This
+happens to us a few times, but we are not alone. We also sometimes welcome a foreign ball onto our
+court as well. 
+
+We have the court for one hour and trust me: that's plenty. I am still coughing a bit from the cold
+remaining after my long week of travels (NLNOT and ESNOG). My heart rate goes up to 160 at times,
+but is usually in the 130s which is tolerable. After the 55min of game time, I seem to have burned
+680kCal and my body is super happy. Well, it also hurts like a _mofo_,  but it is thankful that I
+have put it through its paces. And I am not alone: we set a date for next week Sunday 3rd and the
+10th as well. Mari and I debate buying a racket, but we both think we should maybe play a little bit
+more first. I make her a deal: I will buy her a racket if we play ten times. She reciprocates and
+offers to buy me a racket also. Deal!
+
+At home, Quinn is gathering a box of stuff from the basement. Next week is Hallowe'en, and we are
+practicioners. Remember we bought a few metric tonnes of candy last [[week]({{< ref wk12day4.md >}})]?
+Well, we'll be making little baggies for the kids who come to trick-or-treat at our door.  Quinn
+makes quick work of decorating the front yard with spider webs, our Elza ghoul and a bunch of
+stay-out tape. I add copious amounts of spiders to the webbing and overall think it looks wonderful.
+
+Back inside, I am reminded of a chore I gave myself: tending to my geocache called
+[[Schüracherstutz](https://coord.info/GC657NY)], the container of which has gone missing a while
+ago. I create a new one and add a logbook to it, and make my way over to the little one. Marina asks
+me on the way out to get a bottle of milk in case she needs it for tonight's dinner. I bike over to
+GZ and replace the geocache, then to the Coop Pronto to get some milk, and then through a light
+afernoon Sun back home where Marina has started making a second helping of _Vol au Vent_.
+
+Last week, we were supposed to have Jan-Christiaan and Sandra over for dinner and they were very
+much looking forward to this _Vol au Vent_. In the end, I ate some in our guest room during
+isolation when I was in the full-on [[sick period]({{< ref wk12day6.md >}})]. I couldn't taste a
+thing, and as such, had to report that I did not enjoy it. But lucky me! I get a second chance :)
+
+I prepare for us a soup of butternut pumpkin. This soup has only the pumpkin, one onion and a few
+cups of vegetable stock. I will season it with home made croutons and roasted pumpkin seeds with
+salt. It'll be great. Marina mean while makes little meatballs and cuts the chicken for the sauce.
+She will also be making mocca ice cream with little pieces of Oreo. I'm sure JC and Sandra can
+appreciate that, being the proud owners of oreo.nl.
+
+Our guests arrive at 17:00, on the dot. You can tell we're not the only ones that are _Swissing_! We
+catch up over a suitable _ap&eacute;ro_ of Mattei Cap Corsa, a corsican drink which we first enjoyed
+at their place a few months ago. Before dinner, I show them the flight simulator and take a little
+loop flight from LSMD to LSMD, showing lakes of Greiffensee and Pfaffikersee before turning around
+and landing again. It's a quick tour sharing what I've learned so far of the controls and cockpit.
+
+Dinner is enjoyed. The main course is to die for: I definitely missed out last week, as Marina says
+it tastes exactly the same [no, it doesn't]. The _Vol au Vent_ is fantastic. We chat about work,
+travel, the vacation to the northern american continent that Sandra and JC made, as well as the city
+trips that Marina and I have made over this last Fall. The desert is a mocca ice cream which Marina
+has made herself with her trusty rusty ice cream machine: a good investment!
+
+We agreed not to make it too late today; Sandra and Quinn both have to go to work tomorrow morning
+and JC will be traveling to Dublin. So we go easy on the sauce and by 21:00 or so, we say our
+goodbyes. Marina and I watch one episode of _Lilyhammer_ (my favorite episode by the way, the one
+which takes place in Gjendesheim): Roar gets saved, the brittons take a swim in lake Gjende, and you
+can just see Memurubu and [[Besseggen](https://de.wikipedia.org/wiki/Besseggen)] (which is my
+favorite place on Earth) and Jonny thugs his way through Muriburiland

+I have to say I'm a little bit melancholic seeing that today, week fourteen of my sabbatical, has
+started. My journal is going to be perhaps a bit of an anti climax because I have promised myself
+that in the last week I would not do very many things, but just recompress after having been able to
+let my mind roam free for so many days.
+
+In all my years as an adult, I've never had a vacation longer than three weeks. Ever since working
+at Google, and I started in 2006 mind you, I have mostly spent school vacations traveling with my
+family - in the before times this was to the San Francisco Bay Area, sometimes as well to Sydney
+Australia. I would work mostly, and in the weekends we'd do fun stuff together as a family.
+
+I'm now looking back at the time I spent off-corp, and it's difficult to overstate how valuable it
+has been for me. I've gotten to finish a few projects that have been quietly and patiently waiting
+for my attention in the dusty corner of my work room. I've traveled quite a bit and enjoyed the
+company of many friends, family and network engineers. I also finally cleaned my room&trade;, and I
+got a Roomba vacuum robot called _Suckel_ to help me keep my room tidy. I played wiht lego, although
+not as much as I would've liked. Marina and I drank many martini's in the back yard while the Summer
+was blessing us with good weather, but I did not get to re-design and work on our garden. Tim helped
+me, as an emotional support animal and subject matter expert, to get my flight simulator up and
+running, and I've clocked 20hrs or so of flight time in it. Yesterday I ordered two 31.5" screens
+which will serve as the left and right window. I find VFR difficult without having a lateral view
+out the window of my little simplane. Would you believe those screens were only CHF 120,- apiece?
+Unbelievable!
+
+In the morning I cut a new release of my KVM image for VPP, Bird2 and FRR 10.1. I've included the
+`sFlow` plugin, a working `hsflowd` and some tools like `psampletest` and `sflowtool` in the image.
+While testing, I started an [[Akvorado](https://github.com/akvorado/akvorado)] instance to validate
+that things work. I think there's still a few small things we need to take care of, notably around
+SNMP information and perhaps a few fields in the sFlow counters (such as interface state and speed).
+And for the Akvorado data model, I'll want to feed it some BGP information using
+[[BMP](https://datatracker.ietf.org/doc/html/rfc7854)] so that things like prefixes and
+source/destination AS numbers are known. But, it's a start, and it works.
+
+In the afternoon I spent some time with the simulator. My buddy Luuk pinged me on Signal, and he'll
+be renting a plane this week, intending to fly it up from Lugano where he lives, to Wangen-Lachen,
+airport [[LSPV](https://www.flugplatzwangen.ch/)]. All we need is a bit of good weather, and today
+it's gorgeous out! In the sim, I'm doing attitude control, controlled turns and flying patterns. I
+find it very difficult to keep my altitude, perhaps also because there is no motion feedback in the
+simulator (ie, I don't feel myself going up or down). But I'll get the hang of it, eventually.
+
+There's still a flurry of requests for FreeIX Remote. Lancom in Greece has offered capacity on their
+100G wave from Thessaloniki to Amsterdam, and will be giving all of their local FreeIX Greece
+members (there are half a dozen for the moment), free access to the NIKHEF exchanges. FreeIX Remote
+is slowly growing, with currently 210K IPv4 prefixes and 64K IPv6 prefixes. Not bad for a peer :)
+
+Marina makes a non-typical but delicious meal! She takes butternut squash and onions roasted in the
+oven, with goat's cheese and cured ham on a bed of arugula with a light vinaigrette. She asks me if
+I can fry a beef _Limousin_ steak, which I happily oblige. Together, this makes for a very tasty
+dinner indeed! After dinner, we watch some news and settle down on the couch for a few episodes of
+Lilyhammer.

+
+This morning my buddy Arend sends me a message on Telegram - and asks me if I can check the port in
+Qupra. Oh my deity, it's finally happening! After the general assembly of Coloclue approved a
+member's petition to allow members to install cross connects at Qupra, a few months of "kastje, muur"
+happened, and the networking committee and association board reached an agreement on how this would
+happen.
+
+A few months after that, Arend tried to install a crossconnect but we weren't ready paper-wise. I
+brought it back to the attention of the networking committee and we identified the missing pieces: a
+patch panel with keystones needed to be installed in each rack (and it was only available in two of
+the racks at the time), and a change to the administrative database needed to be added to document
+which members had which crossconnects.
+
+Tim took care of the first thing - he ordered the panels and keystones and went to the datacenter to
+install them. I offered to take careo f the second thing - but since the administrative database has
+need-to-know information, our treasurer Arjan preferred to add the records himself. Once these two
+things were taken care of, all I had to do is wait for a practical moment :) I had planned to deploy
+the fiber myself last week, but I had to cancel my trip to Amsterdam due to the COVID situation.
+
+So I was surprised and delighted that Arend pinged me. The Qupra FrysIX switch was pre-configured,
+and all that was left was to plug things in. Arend made quick work of it, and as well put in the
+cross connect for a few other members at Coloclue, he's such a sweetheart! For me, this link will be
+used to alleviate the hypervisor at Equinix AM3, as it is running low on disk throughput due to me
+using Samsung consumer SSDs. I shipped Arend a few enterprise SAS SSDs before, but he hasn't gotten
+around to deploying them yet. More importantly, the AM3 hypervisor runs FrysIX routeserver, LibreNMS
+and IXPManager.
+
+After the Qupra gig, Arend made his way to NIKHEF where he installed the FrysIX patch for FreeIX
+Remote, directly into the VPP router `nlams0.net.free-ix.net`. That router now has LSIX, SpeedIX,
+and FrysIX connected. I spend some time bringing FreeIX Remote AS50869 into quarantine and then into
+the production VLAN. That's a benefit of running the IXP: I get to expedite my own connections :)
+
+Now that the FreeIX Remote router is connected to FrysIX, I allocate a private VLAN between it and
+IPng's infrastructure. This allows me to create a VPWS (L2VPN, Ethernet over MPLS) on IPng's MPLS
+switches `msw0.nlams0` and `msw1.chrma0` from this router in Amsterdam to the one I already installed
+in Zurich. iBGP comes up, and there are now three routers in play (`nlams0`, `chrma0`, and
+`grskg0`), and amongst them, they know about 207K IPv4 prefixes and 64.7K IPv6 prefixes, and all of
+them can be reached via direct or routeserver peering. How cool is that?
+
+
+```
+pim@nlams0:~$ birdc show route count
+BIRD v2.15.1-4-g280daed5-x ready.
+800934 of 800934 routes for 207438 networks in table master4
+449754 of 449754 routes for 64696 networks in table master6
+1501107 of 1501107 routes for 500369 networks in table t_roa4
+364077 of 364077 routes for 121359 networks in table t_roa6
+Total: 3115872 of 3115872 routes for 893862 networks in 4 tables
+```
+
+In the evening I send a maintenance announcement out to FrysIX members: in the night of Wednesday to
+Thursday of this week, I will move the routeserver RS2 and the IXPManager over to the hypervisor
+at Qupra, which now sports a 10G connection to the FrysIX peering switch there. I have plumbed the
+management VLAN 264 and the Quarantine 2605 and the Peering LAN 2604 through to the hypervisor.
+
+I practice by moving `nms.frys-ix.net` over - this is a non-intrusive change. Using ZFS block device
+replication, I can pump over the boot disk with about 110MB/s, because the hypervisor itself has
+"only" a one gigabit connection. I boot the VM, and it comes up cleanly. Nice. I spend a few hours
+preparing the move of the other two machines (RS2 and IXPManager), which are service impacting. But
+I can start by making a snapshot of the block devices, copy their data over ahead of time, and then
+copy a final snapshot incrementally.
+
+Today was a good day for FrysIX :)

+
+Today I did pretty much nothing :) I spent a bunch of time in the flight simulator flying circuits
+and trying to keep my altitude. Also I did about twenty (flyby) approaches where I would try to have
+a sink rate of 400ft/min and 60kts with flaps at 10 degrees. The airplane is sluggish at this speed,
+so there's a bit of a delay before the correct attitude is reached. Think of it as a really slow PID
+controller. I'm still pretty terrible at it, but at least I am putting the airplane down in one
+piece. Doing visual approach is really difficult by the way, because looking left and right is a bit
+awkward. Seeing as my spiffy video card has four monitor outputs, I think I'll try to get my hands
+on some cheap screens that could serve as left and right windows.
+
+After lunch I take another look at the `sFlow` plugin - for some reason it is emitting large
+interface IDs (1e9 + hw_if_index), but Neil has written it such that if a Linux Control Plane pair
+exists, it'll use the Linux vif_index. Clearly that isn't happening, and I have a pending call with
+him tonight to try to get to the bottom of it.
+
+In the late afternoon, Quinn Marina and I draw smiley faces on our halloween candy baggies, and fill
+them with an inordinate amount of candy. We make 120 baggies, as in previous years, we've often been
+able to offload 100+ of these things to the neighborhood kids, the weather is going to be good
+tomorrow, and Quinn decorated our front porch in a very inviting way: I'm sure the kids will enjoy
+it, but not as much as we will, methinks :)
+
+After dinner, Marina and I watch some news, and then I retire to the basement for my call. I futz a
+bit with the audio, but eventually am able to greet Peter and Neil. We talk about a few operational
+details, notably:
+
+1.   the ability of the `hsflowd` to send its update traffic from a network namespace different to
+the main one (because VPP wants to run in a `dataplane` netns). The tool already supports this,
+yaay!
+1.   if samples are received before the interface counters (with their respective interface IDs
+mapped to the Linux Control Plane vif_index'es, then those samples will arrive at the collector with
+these if_index values of 1000000001 and so on. This will make tools like Akvorado try to retrieve
+SNMP indexes with that - but they won't exist and this is a bug. Neil agrees, and will inhibit
+sending of samples until after the first counter for an interface is found
+1.   a propose the large numbers, they are repeatably and permanemently `1e9+idx` for me, while they
+should really be the LCP vif_index. We add some debug logging, but it doesn't trigger. Then we run
+out of time and we promise each other we'll both look into it offline.
+
+All in all, a super productive meeting, and once again I learned a tonne.
+
+At 23:00 I need to complete the move of the FrysIX virtual machines from my hypervisor at Equinix
+AM3 to another one at Qupra, which Arend connected to FrysIX infrastructure yesterday. This move is
+important, because the SSDs in the AM3 hypervisor are crappy, while the ones in Qupra are enterprise
+SAS-12 SSDs from NetApp: much faster, must higher write rate, much longer durability (famous last
+words).
+
+I take a snapshot copy of `rs2.frys-ix.net` first, and copy that VM to its new spot, but disconnect
+the FrysIX port, by moving the virtio network card from the FrysIX bridge group to an empty bridge
+group. I boot it, and upgrade it from Debian Bullseye to Debian Bookworm while I'm here. I have it
+download its config and at 23:00 exactly, I shutdown the old `rs2` and connect the virtio network
+interface to FrysIX in the new spot. Finally, I add VLAN 2604 (production) and 2605 (quarantine) to
+the port in Qupra, and a few seconds later we're fully online. The migration of `rs2` took about 150
+seconds of downtime. Not bad, eh??
+
+The IXPManager virtual machine is a bit larger, but thanks to ZFS block device snapshots I can make
+an incremental ZFS transfer, halt the old `ixpmanager` VM, quickly `zfs send | zfs recv`  the last
+bits from the penultimate snapshot to HEAD, and boot the VM on its new spot. The IXPManager comes up
+within 10 minutes or so. All in all, the maintenance window lasted from 23:00-23:35 and I was quite
+happy with the results.

+Today is Hallowe'en! When we moved to Br&uuml;ttisellen in 2006, it was _not_ a thing. Over the
+years, a few of us would decorate our houses, but most of the kids were not really with the program:
+no trick or treating, no dressing up in scary costumes, nothing. But when we bought our place in
+2015, we we decided to really decorate in the week of Hallowe'en. These days, kids will come round,
+sometimes in small groups, sometimes in very large ones, parents and all. Many of them still don't
+really know what they are doing: ring doorbell --> get candy. The German way to say _trick or treat_
+by the way is _s&uuml;sses oder saures_ (English: sweet or sour) which I find hilarious because if
+you say "well I choose sour!", the kid will look at you as if you're crazy: "Sir, this is where you
+hand over the candy?!".
+
+> You have much to learn, Switzerland, but I love you!
+
+We have lots of candy in our baggies, we have Elza (our door-ghoul), spiders and lots of spider
+webs, and some UV lights to give them a spooky glow-in-the-dark feeling. I will be dressing up in a
+black hoodie with a _zipperface_, which takes a while to prepare for, but really hits the spot with
+freaking out the children.
+
+In the morning, the doorbell rings at 09:00 and oh look, a package! It's a rather huge package, the
+size of a small refridgerator... in it are two 32" curved screen displays, which I bought for the
+low low price of CHF 120,- apiece! It's amazing how affordable this stuff is! I unpack them, which
+takes actually quite a long time, and take care of the cardboard and styrofoam carnage that ensues.
+After my hard work, two screens are available for the flight sim.
+
+OK, this thing will need to move, because hanging off a screen on the left and right hand side of
+the main screen will make the simulator a lot wider. Luckily, I have a spot, sort of, in the server
+room. There's an unused desk there which I move out of the way. I then move the simulator into the
+room and Marina helps me measure how high the left/right screen need to be. It turns out, 96cm is
+the sweet spot.
+
+I have a few hours left before I need to change my appearance, so after a quick lunch I go to the
+Ikea, as they happen to have a 60cm x 96cm x 30cm cabinet called _Spiksmed_. Did you know that
+almost all the IKEA product names are fake Swedish words? My IKEA in Dietlikon has exactly two of
+these _Spiksmed_ units, so I grab them! The trip takes me only twenty minutes, because I don't have
+to go through the whole maze of the store, rather I can just purchase these items and move to the
+_Warenausgabe_ (English: Goods Distribution), and these little ones are quickly in hand.
+
+At home, the cabinets are pretty quickly assembled, and while I don't have time to play with the
+simulator, I do manage to connect it all and project a left- and righthand door + window on these
+two screens. It looks ... absolutely stunning. Very, very immersive!
+
+Marina interrupts my fun in the basement and suggests that I shave before dressing up, because the
+zipper-face uses latex to glue onto the skin, and I don't want to feel the burn of a brazilian
+face-wax later when removing it. So I shower and shave and put some skin lotion on my face. The plan
+is:
+
+*   15:00-15:45 Marina gives Pim a Zipper Face
+*   15:45-16:15 Pim goes to get Quinn. Marina converts into Sally (from the Nightmare before Christmas)
+*   16:15-17:00 Pim and Quinn return.
+*   17:00-18:00 Marina turns Quinn into Tate Langdon (from American Horror Story)
+*   17:30-18:00 Pim makes dinner
+*   18:00-18:15 Dinner had
+*   18:15-22:30 Freak out the neighborhood kids.
+
+For dinner I make baked beans, potatoes and a chicken schnitzel, it's a simple meal but we don't
+have much time to eat. Most of the younger kids will want to be in bed at 19:00 or so, as it's a
+school night (remember those? School nights, heh). I apply some extra bloody gore after dinner, and
+drink water through a straw. Marina puts on her Sally-wig and grabs Zero, the floating ghost-dog. 
+
+It's fair to say we freak the kids out. It's funny to me because I've seen grownups, teens and
+toddlers all keep their distance and kind of refuse to approach the door. They don't know what's
+going to happen. One set of teenage girls stood a good three meters (ten feet) from the door, and
+when Marina said they had to come get their candy, one of them said - I kid you not - "Oh, no I'm
+good over here, you can throw us the bag of candy, kthx". But we made them approach, anyway :)
+
+Marina and I take an evening stroll through the neighborhood. There's about ten houses or so that
+really put themselves out there; and about twenty houses that are approachable (although, honestly:
+if you want to participate in trick or treating, you really should decorate your house!). It's
+pretty clear to find our house, and many kids do. Some even twice. Or three times.
+
+Quinn and I also take a walk and I often ask him: "Hey Quinn, can I eat that kid over there?", and
+Quinn plays his part too, walking with a cane but then lunging at kids screaming at them. So many
+heart attacks were had. I love it.
+
+At about 22:00 we call it a night. A cute thing about Switzerland is the so called _Nachtruhe_
+(English: night rest), which is a federal law to avoid street noises after 22:00. So we turn off the
+lights and UV, and finish watching the _Adam's Family_ movie that Marina put on while Quinn and I
+were out taking a walk and scaring the neighborhood kids.
+
+We had so much fun today - I'm glad.
