I don't even understand this one, but sometimes I'll be doing something and people will just burst out laughing. It's like I just told the best joke in the world. I get really freaked out, and ask what I did, and they'll always be like, "You have the funniest mannerisms." I use big words, my movements are very flowing, and I make a lot of really quick facial expressions and hand flails whenever I get exasperated. People find it hilarious, but I truly and deeply feel uncomfortable when they laugh.
I like to lie to people. Not for personal gain, just to see if they will catch me.
I talk to myself a lot.
I don't like it when people touch me.
I'm either completely calm or extremely emotional. There's no in between with me really. Either stoneface calm and uncaring or my-hands-are-shaking pissed off.
I use really big words sometimes, and people get really confused and think I'm a freak. (pragmatic, moot, extrapolate, etc)
I also read people's facial expressions and body language. It's very interesting and provides me with a lot of info about people.
