One of my newsletters snipped a bit of an old essay (from 2013 about parenting). The whole thing is apparently behind WaPo’s paywall, but just the snippet I read was pretty moving. Author: Mike Gerson, a writer on religion and politics (and apparently parenting) who recently passed away.

Eventually, the cosmologists assure us, our sun and all suns will consume their fuel, violently explode and then become cold and dark. Matter itself will evaporate into the void and the universe will become desolate for the rest of time.

This was the general drift of my thoughts as my wife and I dropped off my eldest son as a freshman at college. I put on my best face. But it is the worst thing that time has done to me so far. That moment at the dorm is implied at the kindergarten door, at the gates of summer camp, at every ritual of parting and independence. But it comes as surprising as a thief, taking what you value most. . . .

I know this is hard on him as well. He will be homesick, as I was (intensely) as a freshman. An education expert once told me that among the greatest fears of college students is they won’t have a room at home to return to. They want to keep a beachhead in their former life.

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.

There is no use brooding about it. I’m sure my father realized it at a similar moment. And I certainly didn’t notice or empathize. At first, he was a giant who held my hand and filled my sky. Then a middle-aged man who paid my bills. Now, decades after his passing, a much-loved shadow. But I can remember the last time I hugged him in the front hallway of his home, where I always had a room. It is a memory of warmth. I can only hope to leave my son the same.

Parenthood offers many lessons in patience and sacrifice. But ultimately, it is a lesson in humility. The very best thing about your life is a short stage in someone else’s story. And it is enough.
