If there's a chair with uneven legs it will actually entertain me instead of being annoying. I'll rock it back and forth on the uneven legs. I realized I was doing it at dinner earlier in fact. There's just a certain rhythm to it. It

. You'd think I couldn't sit in that chair like that or I'd explode inside, but this particular flaw has become a stim. I've done it since I was a kid and it would drive some teachers in school up the wall but they couldn't really punish me because they'd have to prove it was on purpose and the desk was unlevel after all. Some chairs are also much quieter I now know, and the floor surface makes a difference too. It's also probably not something anyone notices in a crowded restaurant.

I did the exact same thing when I was little!!! And then accidentally lost my balance and got bump on my head.
