Habits (for people with living with aspergers)

I know that repetitive behaviour comes into living with AS. We have habits that everybody with AS may call unusual. I think they are anyway.

Anyway i made this thread so people with AS could talk about what kind of unusual habits they may have.

Mine include twisting things in sight such as straps on a bag, playing with things in sight such as a mat (what you will put a cup on, or plate) and chewing things in sight (such as the metal on a key ring)

What kind of unusual habits do you people on AS have?
