Confession: I'm a nail-biter. I bite them ALL THE TIME. If you think about it, you've probably seen me at it. It's annoying, because I never realize I'm doing it until I've got like halfway through the nail, and there's no turning back after that. I've tried to stop a few many times, but it doesn't look like it's happening. Oh well.
Also, I'm self-conscious about my wrinkly hands.
On a more serious note, I avoid conflict, usually by bottling up my emotions. I judge "weird" people before I get to know them. I rush through everything. I don't wash the dishes every night. I procrastinate. I'm easily jealous. I can be selfish. I also eat when I'm bored.
