Agreed ! Chara's "annoying" habit is just cute!
Mine... hmm, let's see. I have this thing about wrinkles on clothing. I cannot, no matter under what circumstances, wear wrinkled clothes. So yes; I iron everything I wear, including my socks :O! It's quite annoying, actually, because if I'm in a rush and the shirt I wanted to wear is wrinkled, I either have to iron it or find something else, which diminishes my time even more.
Other things would be my intense procrastination. I do
everything at the last minute, which makes me be all frantic and what have you.
Bitting my nails, touching things at department stores with the "don't touch sign", chewing my pens during class, and misplacing things are all habits of mine that I don't really enjoy. *sigh*
