oh god, i used to be so bad with it as a kid, i had my GP tell me off for it as i was getting a bald spot on the back of my head in just one place. So i got scared and stopped, but it felt 'wrong' to me, it made me feel a bit hibbly jibbly inside. So instead i run my fingers through my hair for loose stands and wrap it round my fingernails and fingers instead and its comforting and also an unconcious habit. Lots of people see me do it and quite a few people ask what am i doing, why do i do that, etc. And to be honest when i give them the answer, they look at me weirdly. eh, nevermind.
