A year ago, a friend of mine whose child had just graduated from high school suggested I write an article about this big milestone. I thought about it and decided to wait. It would have been like writing a guidebook about Paris based on internet research, without actually going there and seeing the light, smelling the bread. A year later, my son has just graduated from high school. Let's just say I've seen the light. I assume that's why there are tears in my eyes all the time.
