This is such a nice idea for a thread.
Dunno if I'd want to be by myself or with my partner. She's not a caregiver but she does understand me really well (if we're in a store with a toy aisle, she already knows we're taking a quick trip through it! Or she'll let me pick out a toy or candy if I've been "good" - which cracks me up because again she's not into it and she's teasing me a little but not in a mean way, she just says I'm cute) but she's also not into doing "kid" stuff.
Soooooooo I might just hang out by myself. I don't ever really get time that's just me and no one else in the space, so I'm rarely able to just relax as myself when I want to. It'd be nice to not have to be on edge the whole time.
The most fun thing would be, I think, make the same breakfast I always had as a kid when I'd get up before sunrise to watch cartoons on Saturdays (...honey nut cheerios and water, not very exciting but the thing was I got to pretend to be a puppy while I ate it...I did not use a spoon then and I don't now!) Then I'd try to find my favorite cartoons streaming somewhere (I always wished streaming services had some kind of randomized playlist feature where you could add a bunch of episodes, maybe from different shows, and let them play at random, like you were really watching TV back in my day! Probably not practical though.) Or oldschool Sesame Street or Mr. Rogers or Fraggle Rock, I guess it wouldn't have to be cartoons. A couch cushion fort would be ideal...alas my current sofa has attached cushions, so blanket nest it is!
I'd talk my partner into going to the zoo with me right before it opens and I'd pack lunches for us (she's vegan so I'd probably do peanut butter sandwiches on whole wheat instead of my other little staples that involve meat or dairy, and I'd bring Chessman cookies for myself but idk if she can eat those, I don't think so, so we'd have to plan what else to bring her) so we could stay until it closed. In reality she probably wouldn't want to do that, but I'm not actually going to make her! I'd pick a day it wouldn't be too crowded so we could get right up close to everything and I could show her all my favorite animals. I mean they're all my favorites, but the red pandas and the snow leopards are my FAVORITES. And the sea lions, especially when it's feeding time. We'd go to the children's zoo cuz I know she likes petting and feeding the animals (I did when I was actually a kid but now I'm afraid of getting bit!) and they have a lot of fun educational things she could try ; she really likes sensory stuff and she didn't get to have a very fun childhood so I bet she'd like to try it now. Specially the speakers where you can hear things like you would if you were a fennec fox, cuz she really loves them. (Me too actually, they're so cute.) And I'd let her get something from the ice cream cart cuz food is her favorite and since this day is MY favorite things, I'll treat her to whatever she wants.
Unfortunately my body doesn't work all that well so we'd have to go home after that and it would probably end up being a race to see who fell asleep on the couch first. The one left awake would have to order dinner (I'm always the one awake so we're getting pizza! From the place I like! I love her but she has terrible taste in pizza.) Then while I was waiting for food to get here before I'd have to wake her up, I could take the time to look at books or color or play Animal Crossing and chill out a little. Being outside around people makes me tired. I need a lot of quiet after.
Then after dinner (we'd probably watch something we both like during! cuz it's not my perfect day if she's not having fun too! and god knows she wouldn't be having it at the zoo for six hours! but hey i mean it's still MY perfect day
) maaaaaaaybe I'd talk her into reading to me and giving me snuggles. (She's kinda used to just having me cling to her all the time anyway. I can't help it, she's my favorite!)
Then at bedtime I would get to fall asleep first! Which isn't a thing you can choose I guess but I always fall asleep before she does and I have a hard time falling asleep when everyone else is asleep. I would either ask her to read to me more or put on the relaxation app I like (it has a meditation about cats on a marina and tells about the kitties! It's really cute.) Usually I like to sleep with the TV on but if I get to fall asleep to her being awake I wouldn't need it. I don't get to see her very much cuz of stupid covid so mostly that's all I want.
