"What are nuns doing on the beach on a cold, windy day?" my friend asked. "Good question!" I said. Then I asked myself, "what was I doing on the beach on a cold, windy day?"
They were probably doing the same thing I was, which was getting away from the places one might expect to find me, for some introspection and nature. Nothing more.
I remember that day pretty clearly. I was mostly alone, except for the nuns and a couple with a dog. I sat on a naturally occurring dune chair for a while, staring at the frozen lake and thinking about the past that had brought me to this point. I made my peace with it, saw the nuns, took a photo, and went home.
