CLAUDIA AND TENTOO (friend)SHIP
collects rocks: not really either of them, maybe tentoo a bit if they figure out the rocks are different compositions than the one's in their universe (which they'd probably figure out by licking tbh)
takes pictures of the other while they’re asleep: Claudia
gets drunk and breaks shit: definitely Tentoo
can’t swim: Tentoo sort of just because they're like "what the fuck why the hell do you have to breathe so often when you're swimming this is completely inefficient and difficult human lungs are ridiculous"
remembers to feed the fish: Claudia?
puts up Christmas decorations in November: both of them tbh same with halloween being early
sends inappropriate texts and SnapChats while the other is in a meeting: not really inappropriate but tentoo would probably keep sending things while claudias trying to do caretaker duties like "look at this look how far i am into building this thing"
makes Sims just to drown them in the pool: Claudia maybe?
brings the other coffee at work: neither mostly because Tentoo just hogs all the coffee even though people try to keep it from them they've probably got a secret stash hidden in the warehouse somewhere
takes gym locker room selfies: neither
signs them up for tennis lessons and a salsa-making class: also neither they're too busy inventing things together
forgets to charge the other’s iPad and leaves it dead on the coffee table: neither, what do you take them for-- they've probably invented something so they don't have to charge the stuff ever again
