lol, i'm just going down the list ticking things off...
My lips are pretty sensitive so they chap easily and are prone to cold sores, not fun at all
.
I've always got at least one leg vibrating like a dead dog, I do it subconsciously and get yelled at all the time cause it can actually get pretty violent, lol i've rocked entire rows of seats as well as cars i'm in without noticing :$
I started cracking my knuckles when i first got into high school, pretty much a stress thing, it got really bad mid way through were i was just doing it non stop, got past it though, I still do it, but only occasionaly, when i feel "aww crap".
I'm sure there are more, lol i'm OCD about everything really.
