I still eat, sleep, and shit.
I use a french fry to scrape those nasty onions off my McDonald’s cheeseburger, then stuff about a dozen french fries in on top of the burger, under the top bun. Always done that, no idea when or why I started.
I still love swings and swing-related acrobatics, dying to try that anti-gravity yoga.
Every Christmas I get the urge to buy a Christmas coloring book and a new box of crayons. Some years I succumb, some years not (this year not - sigh)
Also as previously mentioned, I’ve had library cards since age 5, and still am a voracious reader.
My stuffed animals have morphed into plain old pillows.
Run around the house.
Watch cartoons.
Play video games.
Listen to AC/DC and the Stones.
Ride bikes.
Look over my shoulder when Don Henley sings “Don’t look back, you can never look back” in “The Boys of Summer.”
I eat the bad stuff first, just to get it out of the way. Then, after the meal, what I remember most is the good stuff . . . and there’s always room for good stuff!
Not much, but I still enjoy a big bowl of spaghetti, watching science fiction on TV, and if it’s not a big deal, scrape off the ketchup from whatever civilization thinks ketchup goes with, and use mustard instead.
Sometimes I put a hose on the driveway, with just a trickle of water coming out of it. Then I become a giant, and follow that stream as it forms lakes and rivers, all the way down to the street. Sometimes I add a little dirt to make a dam or island, or a leaf can become a boat.
I sleep with a stuffed animal.
I sometimes climb trees at the park.
If no one is around, I like to get from my car to the house by running as fast as I can - how do grown ups resist doing that? It’s FUN!
I still laugh at really immature stuff - like today my nephew said, “Have you guys ever heard of the Fart Police? They arrest anyone who farts. But they let you go if they find out you just had a duck in your pants.” I lost it for, like, five minutes straight.
I still talk to myself when I’m alone. Finally, some intelligent conversation, you know? And I almost always agree with myself. Almost.
How did I forget this one… I’ve never been a litter bug.
Also-
Practice appropriate toilet seat protocol when ladies are around.
Have never worn a pair of those “tighty whities”.
I have pre-converstations. Although, I think people do this naturally.
I often look disorganized, but I know where everything is.
I can’t dance well, but have perfect rhythm.
I still have clean handwriting.
My handwriting SUCKS as much as it did when I was 5
When I am behind someone I know, I will tap one shoulder, and jump to the other side. People think once you’ve hit 22 you stop this…not I!!
Ice cream. It’s all about the ice cream. Still eat it every chance I get. I also still read kids books sometimes.
Having kids of your own is a great reason - not that anyone needs it - to read kids’ books and watch cartoons with them.
I wear Hello Kitty pjs almost exclusively and I like to reread all of my favorite childhood books whenever possible.
After I load the groceries into the car, I run with the shopping cart and ride the back of it to the cart corral.
I daydream.
Play video games.
When I’m at the beach I MUST dig a big hole. It’s pretty much the only thing you CAN do at Oregon beaches besides fly kites. Even in the height of summer that damn water is 33º
Fly kites.
I play with Legos (yes I know that’s technically grammatically incorrect, bite me)
I have “yea huh” and “nuh uh” types of arguments.
I also use The Force to open doors and elevators. Also to change stoplights.
OK slight derail; One time I was writing a check for some merchandise at an electronics store, and the girl asked me for my identification. I did the Jedi Wave and said with a completely straight face, “You don’t need to see my identification”. She said “I don’t need to see your identification”. I left it as that, I didn’t want to press my luck 
Eat oranges by cutting them in quarters and putting the quarter in my mouth whole, peel facing out, so that I look like a monkey.
Occasionally, when eating broccoli, I am a giant eating trees.
Slide down banisters when I get the chance.
Draw faces with ketchup and other condiments.
That’s about it, really.
I do that out of habit these days.
I MUST make relly elaborate sandcastles.
Having a kid, I do end up playing a lot of kids’ games and with kids’ toys, but the fun level wears off pretty quickly - at least in comparison to how much fun it is for my child.
I still have a soft spot for baby dolls… not like those doll-collector ladies who have the creepy ones displayed everywhere, but I always hold them gently like a baby, all mine that are in storage are carefully placed so that they’re face-up and not squished and nothing is on top of them.
Any time I get something new, I still want to open it RIGHT AWAY. Even if it’s something that will not be useful right away or if it’s something really boring. If I can’t open it, I at least have to take it out and look at it. Read the package, examine my loot, think about what I plan to do with it, etc.
If I see something climbable, I climb it. Walls, trees, anything. The higher the better.
I still use the curb as a balance beam. And if there’s some kind of raised wall next to the sidewalk, I walk on top of it instead of on the sidewalk and then jump off at the end.
I still love buttons. I want to push the elevator button, I want to push the button that’s supposed to make the light turn green, etc. There’s a button at the gym that unlocks a gate and I’m always disappointed when someone leaves the gate open just a little and I have no reason to push the button.
eta:
this too. Though I don’t spend a lot of time at beaches, I do love digging holes and making piles.
My brother! I also change the traffic lights using this medium.
I thought I was the only person in the world who did this.
I eat cereal just before bedtime almost every night.
We didn’t have video games when I was a kid. Instead, I’m teaching my children to play all the classic board games that I loved, like Clue, Monopoly, and Risk.
Even though I don’t consider myself at all superstitious, I still find myself subconsciously avoiding sidewalk cracks. It irritates the hell out of me.
