(I was in the bathroom anyways earlier so I took a look, and it seemed to stop when I looked at it. But when I think about it without looking at it, it seems to get worse. I think it comes from glaring too much. On the upside, my recent attitude change seems to have lessened my "I'm a New Yorker, fuck off and get out of my way" glare that I take on unconsciously when walking around outside. It was much less noticeable than previously, at least in the mirror.)
So far, I haven't started in on the furtive glances or maniacal laughing, but I'll keep you all posted as to my progress.
