I tend to slouch right over, feet and knees together usually bouncing on the balls of my feet.
Hands in my pockets with fists clenched, or fiddling with my keys in my lap.
I'm either looking down at my feet or staring right out the window.
It kinda feels like i'm trying to make my self as small as possible and not be noticed -not easy when there's only two of you in the room.
