Given: Oakland, CA

Today I was stopped at a crosswalk and a very elderly woman with a walker was standing at the light.  When the light turned green, she hesitated and turned to the man standing next to her and said something to him.  He walked with her very slowly across the street.  After we all crossed the street, I watched him take off in a different direction from the woman.  Apparently they didn't know each other and he had taken the time to help her cross the street.  I chased him down and handed him a token and thanked him for helping her cross the street.  He looked very puzzled, then read the token and smiled.
