Do you have a nervous habit?
Submitted by Herding Cats.

I wouldn’t exactly call this nervous or anything because I do it all the time, but I tend to chew on pens. I have no idea when and where it started, but if I don’t have some gum in my mouth and there’s a pen hanging around somewhere that I’m using, I’m probably going to be chewing on it after a while.

Perhaps I’m nervous all the time? Anyway, I’ve found that chewing gum helps a lot since I don’t chew on two things at once.
