random subway story

I was on the subway recently doing one of my little logic puzzles and a man sat down next to me. I didn't pay attention to him until he asked what kind of puzzle I was doing. (they are called "paint by numbers" - I am addicted) He then continued on to say that he had seen me earlier that day on the downtown train doing them. I laughed and said we must have the same schedule. The coincidence made me smile.
