I ramble on and on when I am nervous. I also tend to complain alot when I am stressed. =D.
When I am thinking I pace and talk to myself.
Guilty of that too.
I'm also a compulsive chewer, especially when it comes to headphone >.> I sware, one day when I'm using them, I'm gonna chew right through it and electrocute myself, and funnily enough, that thought is still not stopping me from doing it.
When I'm standing still, I tend to fidget my legs, by either doing little crouches or just hoping from one leg to another.
I also have a tendency to flare my nostrils when I'm bored.
Wow, I must be a pretty irritating person to be around
