I chew on my inner cheeks occasionally, usually after brushing my teeth in the morning.
When I take showers, I tend to pull the curtain back to see if anyone is in the bathroom about half way through the shower. I have done this up to 10 times in one showering.
I almost always have to correct someone if they make a mistake or state something incorrectly.
If a family member does something a different way than I would, I try to "show" them how its done.
I pop my knuckles, back, neck, jaw, toes and knees when I'm really bored or very nervous.
I can watch a movie at home 20 times before I watch another movie, but I cannot watch a movie more than once in theaters.
When I'm bored, mostly while driving, I will mimick the exhaust of a "race car". done this since I was a little kid.
before i ask someone something i feel is very important i will spend hours if not days rehearsing what i want to say in my head, but when i open my mouth to say it... it ends up completely different.
i hate when people move or change things around in my "personal" space, such as car, room, desk, work area, etc.... If I have to move my seat in my car forward or recline it, I get frustrated. I even get upset when people who borrow work cars readjust the seats or stereo because I have to then sit there and redo it all the way I want it, despite it not being my own car.
when i shower i always wash my hair, then my face, then my torso, on down to my feet, then I shave. i dry off the same way, head down to my feet. oh and i can't go a day without showering, it ruins my entire day if i am unable to shower in the morning. but i hate to brush my teeth, brushing my teeth to me would be like doing homework, but i do it anyhow.
i guess i am really weird.... never thought about it
*Edit: oh thought of another one.... I always, always always have to eat the Ice in my drinks. I hate to throw ice out.
