I was walking around downtown with my friends one day. I noticed a bum sitting off to the side of the sidewalk. As I started to pass him, I felt my boot connect with something. It was his change can, he had had it out in front of him. I paused for a second then went back to walking, catching up with my friends who hadn't noticed. I looked back to see the bum scrambling around the crowded sidewalk for his change.
