That Dirty Ol Habit

There's many a time when we do things out of pure habit... looking at your wrist repeatedly despite not having a watch on; adding salt when there's already ENOUGH in the dish and thus insulting the chef (moi); or adding tomato ketchup to EVERYTHING you eat, including steak :s (I swear that's not solely due to a preference in taste... )

My biggest habit would be chewing on my thumb nail when I'm thinking or when I'm upset. I'm surprised I've not ripped the entire thing off by now.

I've forgotten what I'm supposed to get at. Damn.
