Habits. Did you have any?

[JustinWilliams]

I went through probably 10 different habits during my highschool years i suspect all trigged by different things.
I caught some from stress i think and most of the others by mimicking other peoples habits. I'm not talking about smoking or drugs either there addictions.
The worst ones i had were biting nails, humming and licking my lips until they were raw and painful if i didt continue licking them.

Ive met some other bizarre habbits my friends had, which some i think crossed into OCD. I had a friend that pulled a down syndrome like face and blew bubbles out of his bottom lip with his tongue, it made me almost crack up laughing everytime i saw it because he was perfectly normal kid besides his habit. How would he have caught it?

I wanna know of other peoples habit stories
