Some years back my mother flew to Florida with JB and me. It was only the second time she had been in an airplane. She kept staring out the window, silent, staring down at the clouds below, until she finally said, with all the wonder she could muster, "I never knew there were two skies."
She meant it. It was one of those moments. Almost everyone sitting around and near us turned and smiled. I can't remember if I corrected her or not. I think I just smiled too.
