Glasses

When I feel uncomfortable, I adjust my glasses. Not out of necessity, but just to give my hands something to do. My left hand moves up to the left corner of the frame (I think that part is called the temple) and pushes them up the bridge of my nose.

I think that is the sole circumstance in which I do this (again outside of necessity).

Even when I'm not wearing glasses, I have to stop myself from bringing my hand up. If it has already made its way there but I am not wearing glasses, I pretend like I need to scratch my head.
