Alrighty, time for the question du jour...a habit that I wish I didn't have.
I try not to call attention to it, but here goes. I wish I didn't have the habit of picking at my fingernails and tearing them off. If you looked at my hands, you'd probably assume that I bite them - but I don't, never have. Actually, they're not as short as those of most nail biters I know. But they're still short and, to my mind, not terribly attractive.
I've been doing it ever since I was a little kid - maybe four or five. I don't remember exactly when or why it started, but I've tried several times to stop and it hasn't worked yet. I mostly do it when I'm nervous or bored, and then I barely even realize that I'm doing it...and it's awfully hard to stop doing something that's practically subconscious.
So just don't look at my hands, okay?
