Hmm, let's think.
I do the hair twirling thing, too. Actually, when it was first mentioned, I started twirling my hair. It makes me look like and absolute doofus, but when I get bored, I have to do something with my hands. That's another thing. I'm constantly moving, rocking back and forth. I look like I'm insane.
When I sleep, the temperature in my room has to be colder than it is in my sheets, or I can't sleep. I can't be overheated, otherwise I wake up every hour or so.
I have to have my TV on mute when I sleep. I have to have certain amount of light. And it has to be completely silent, or I don't sleep. At all. I also have to wrap my arms around something, like my teddy bear.
I also eat hunks of sharp cheddar dipped in honey mustard dressing from Wendy's.
I'm a severe neatfreak. Everything has to be in its place or I go friggin' crazy. My room is spotless.
