It was a little sideways surge in foot traffic that forced me to step directly over his leg.  His feet were bare.  Impossible to ignore his toes:  gnarled and crusty little snails without shells.  I looked down on the top of his head as I passed.  No more than an instant and I’m gone. Earlier, from the safety of the other side of the street while cars sniffed each other and we waited for the Green Man to usher us across, I’d been watching him with a growing sense of anxiety.
