Bus stop dance

I wish I had been close enough to video with my cell phone what I witnessed the other day. A man sitting at a bus stop started out reaching side to side and overhead and twisting in what were obviously stretches. Then he kept going, gesturing to one side and then the other with both arms, repeating the stretches etc. It's really fun to see spontaneous "site-specific" dances like that, even if the guy did look a little crazy probably to the rest of the folks driving by!
