I saw him when I was driving through the intersection by Alewife Station. He was collecting money. I hit a red light and gave him some quarters. He then stopped by for a portrait. I have a fascination with the people that walk this intersection. How did they get here? Where do they sleep at night? What makes them smile each day? Before I had the chance to talk, the light turned green. I guess my questions will have to be answered another day.
