Just thinking again; Dangerous

Just thinking again. Dangerous.
I move away and people's children grow up.
Former students become parents and post their kids' pictures on Facebook.
I become friends on Facebook with the children of my cousins in California whom I have never met and have only seen their pictures when they were toddlers.

I move away and everybody gets old.
(I don't, of course.)
I move home and stay home longer than I ever lived anywhere.
Think I've moved around too much.
Wish I could be everywhere at once.
But today I got two fan letters from second-graders and my life is complete.
