Stuff with symmetry, and it really drives me insane. If I brush by something and it hits my right leg, I have to go by it again so my left leg will hit it as well.

Same thing for if I have an itch or something on one side of my body, like my arm, I will suddenly get or need to scratch an itch on the opposite side in the same place. If I'm sliding a drawer in and I don't feel it went evenly into the space on both sides, I'll reopen it and close it again until I feel like it does. Sometimes I do things with light switches being turned off and on a certain number of times, but my room now has a fading switch so that isn't a problem so much anymore!
Typing this out makes me feel cray.
