I would consider laughing at atrociously bad puns something that's still very childish, but something I find as a (somewhat irresistible) guilty pleasure. Beyond that, I can't say I would do anything else childish; anything else with a 'childish' label applied to it would be something I'm instinctually repelled (or worse, repulsed) by. I'm definitely not a child by anyone's stretch of the imagination.
I have a lucky Giratina card that I have taken to my PAT tests and other important things. It might not help, but it's certainly not hurting. I still spin in spinny chairs. They should not make them so fun to use. #MissingNo
I have a favorite stuffed animal still that I keep at my bedside. It's a Stitch Plush from Lilo and Stitch. I also prefer to have music playing as I fall asleep; it's classical/Baby Bach most of the time, but the background noise really does help one pass out.
I'm a toy collector/photographer so I have many many toys. So many. I have a hobby room to display them though so it's all good. I still sleep with plushies in my bed. I have Pokémon socks that I love to wear (one pair with Pikachu, one pair with bulba, one pair with charmander, one pair with squirtle and one pair with a Pokéball) And Pokémon pjs. I
I Current Have Some Pokémon Anime First Season VCDs.My Family Got It From Someone When I Was Young(Around Age Of 9 To 11).
I have trouble sharing things, does that count? Like, if you want some of my food I'm more likely to just give you the whole thing than split it. I also like to skate across the floor in socks
I have a very large collection of beanie babies and other stuffed animals and Pokémon plushies. They'll be collector's items someday but I will never sell them.
I still play with all the airplane models I have in my room. Sometimes I'll be making jet engine noises when someone else walks inside the house
I still collect plushies. Well, only Pokémon plushies. I donated the majority to the local animal shelter for the smaller animals to have a buddy, but I can't let go of my Pokémon Plushies.
I still collect Pokémon plushies and I even hug them from time to time when I'm having a really terrible day. I can't really help it though.
I still have a hobby for collecting Pokémon cards, which makes everyone around me think I'm childish. Despite that, I still love to collect Pokémon cards. I also have difficulty selling them because of emotional attachment.
Vey attached to all my clothes and get very let's just say childish (not saying the real word) when people tell me get rid of them
I'd say for me it's still making noises whenever I'm startled/something happens. I know I shouldn't be doing it anymore, but I really can't see myself staying silent when I drop something or I dodge out of someone's way...
I still love plushies, and I even collect them. I have a bunch from my childhood as well, including my first even plushie, a duck I called Gum for some reason, and a plush of Pilchard from Bob the Builder. I love cartoons to, and I'll admit I still love Pingu. Such a cute show.
Nothing I do is childish because despite being immature things, I do them very maturely. I take absolutely perfect care of my roughly 18 stuffed animals. I am easily one of the best Pokémon battlers in my school, and consider it the only sport I am good at. I like puns, music that isn't trashy rap, and cartoons, yet I am sophisticated in my discussions of them. I don't spam puns at any opportunity like Internet fools do with bad memes, and I only tell people that their opinions about good music are garbage if they actually are. Which is almost everyone I know. I am not childish. Everything I do and like may be, but since I act with such awesomeness and elegance, I am not.
I still will watch old cartoons when they come on like Thundarr, the Herculoids, etc etc which don't particularly hold up. Also still enjoy the Flintstones, but I think that holds up and crosses age boundaries for more than just nostalgia being basically a cartoon version of the Honeymooners and all.
