I like to have a cat second personality. Often called the evil kitteh of doomz.
I often model and make faces in front of the mirror. *Embarrassing*
I used to wrap my fingers with cling film when eating certain foods because I couldn't stand touching it.
Like HoneyPie I did munch/suck on paper cups, only in my case it was muffins. I haven't had one in ages, but I'm sure I would still do it!
Can't think of anything else for now.
