I HAVE to go to a bathroom and pop a pimple if I discover one by feel, if I don't, I can't concentrate on anything unless it's something super exciting or important.

sometimes in class, I let the lead out of my pencil and gently poke my face repetitively about 1mm apart all over my face until it starts feeling numb, but this is because it has an acupuncture-like effect and it relaxes my face muscles(actually a massage on some levels)

i disassemble pens fully and reasssemble them over and over if I am near one. This is only if I am staying in one place, i.e. class, a meeting with people, a movie, eating in a restaurant, etc.

if I am listing reasons to do or to not do something and I choose the A and B format, I must list three things andd have an A B and C i.e. you shouldn't get a tattoo because A) they're permanent and you might not know what you want in life right now B) it can get infected and C) they cost money, even though the C option barely matters at all, I had to include it to have a C, the same thing happens if I have a REALLY good 4th reason, I refuse to mention it cause I don't want a D option, I have to bring it up later when the subject is dropped like "oh not to mention a face tattoo would make it hard to get a job working with people."

I can't stand when the A/C vents i the car aren't all centered when the A.C./Heater are off. At the AJC auto show I realized a lot of cars had closable vents, and I closed and centered all of the vents in every car I sat in.

I lock the door to anything after I walk through it no matter what. Even f I'm alone in my house I'll lock the bathroom door. I do this when I get in/out of the car, leave the house even just to go get something out of the car for 5 seconds, etc.
