One evening, two girlfriends and I went to a nightclub, only to find the place packed with young people. At 40, we felt old, but before we could make a dignified exit, a tall, handsome man approached us.

"Perhaps we were being a little hasty in leaving," I thought.

Then with a big smile, the man extended his hand to one of my friends and said, "Hello. Remember me? You taught me in third grade."
