Michael Gerson, in the opinion pages of The Washington Post, writes about his son leaving for college:

But with due respect to my son’s feelings, I have the worse of it. I know something he doesn’t — not quite a secret, but incomprehensible to the young. He is experiencing the adjustments that come with beginnings. His life is starting for real. I have begun the long letting go. Put another way: He has a wonderful future in which my part naturally diminishes. I have no possible future that is better without him close.
