He presented me with a puzzle -- all because he waved to me like someone does on seeing a close friend.A big,bright smile accompanied his wave.For the next few days I tried to study his face to see if I knew him.I didn’t.Perhaps he had mistaken me for someone else.By the time I contented myself with the conclusion that he and I were strangers,we were greeting each other warmly every morning like old friends.
