While floating in the calm, salty water at Villefranche-sur-Mer, not quite warm enough to put you to sleep, I had a memory as I gazed up at the rocky hills, dotted with stucco villas and trees. It was about cutting someone off in a way, in a car, or maybe not—I saw a diagram of it in my mind. Something involving some Italians. It was combative,  contentious. But it never happened—did it? What could it mean? Or did it happen in a dream?
