This morning on the train a couple sat next to me with their toddler. When the father and the child got off, the doors closed and the mother stood up and looked out of the window and waved. I’m always interested in how people say goodbye to each other on the subway. Sometimes, you’ll see a couple kiss and even before one has left the train, they have both stopped looking at each other.

I always look.

When I was growing up, we had a dog who would chase our car whenever we left home. More than a few times, I’ve gotten off the train and said goodbye to my wife, and then run down the platform as a goof to crack her up. That’s my job, make the wife smile, keep her laughing. Or maybe it’s just the K-9 in me.
