tonight when i came back into the office after one of my company private clases, one of my co-workers said to me "smile" and i gave her a halfhearted attempt at a smile. she said "what's wrong? you look like you're about to kill someone". funny thing is i didn't feel particular angry, a little tired, but not unusually angry. i don't think this is a good thing. what if i am angry and don't even realize it? maybe the inner hulk in me is appearing without me realizing it? scary thought.
