I was waiting in line behind a smartly dressed -- dockers, polo shirt, loafers -- black man in his middle 30s. The clerk left the desk leaving myself and the black guy alone in the room. After a couple minutes he started to do this little dance for no reason that I could see. And it wasn't like he was acting out a dance routine in his head; it was just random movements. I stared, I couldn't help myself. After a bit he glanced at me and suddenly stopped moving, regaining the semblance of civilization that he normally conveyed. He could act like he belonged in polite society but the real ape was never very far from the surface.
