Grandson Nathaniel asked me a question that I couldn’t answer immediately. As I thought about it, he watched my face.

He said, “You know, Gran, your face is like a computer screen. The icon is there, and the little circle on it just keeps going round and round.”

I laughed, because I knew it was true. He didn’t realize it, but he was in luck that time. I gave him a reasonable answer. If he had questioned me an hour later, he might have gotten a blank blue screen.
