Seventh grade when I was like 12 feels like a week ago to me. And being 15-16 still feels like yesterday. It doesn't always show online, but I definitely behave and look younger than I am in person. No differently from when I was in my teens, prankster tendencies and all. Including terrorizing the neighborhood by singing Re: Your Brains and similar out of car windows for s**ts and giggles.
And I have bursts of outright childishness. Like, I had this running gag for a bit with my ex-girlfriend where I'd randomly finish sentences with "beaver" out of nowhere (e.g. "I went to the store and got peanut butter, chicken, and beavers") and giggle at her reaction, on some level I thought it was kind of hilarious. I only retired it when it was clearly getting stale and annoying, and even then I squeezed some last-minute life out of it by replacing it with "turtle" a few times. Also funny-faces can be kind of amusing.
What's my age again?

Don't believe the gender tag. I was born intersex and identify as queer, girl-leaning. So while I can sometimes present as an effeminate guy, that's less than half the time and if anything I'd prefer it say "female" of the two choices offered. I can't change it though, it's bugged.
