Nothing reminds you you’re an adult like hanging out with a bunch of kids. On a field trip. In a school bus. It’s chaotic chatter — like birds in the trees — until one child starts humming Beethoven’s Ninth Symphony. Why Beethoven’s Ninth? And then they all start to join in, one after another. Only … wait a minute … no, they’re not humming. They’re moo-ing. They are all moo-ing like cows! Beethoven! All of them now. Every last one. The bus is filled with the sound of bovines. And I just have to smile. Nothing reminds you you’re an adult like hanging out with a bunch of kids.
