This is me and Kris Sienkowski, my dive instructor. It was only us two and the boat driver, who was Filipino. Kris and I went for a dive, and when we came up my sunglasses, which I'd laid carefully on the bench, were gone. We looked around for them for awhile. I hated to admit it, but I began to suspect the boat driver, because it was difficult for me to imagine the glasses had committed suicided by jumping off the bench into the water. Just as I was thinking this, the driver's phone gave some kind of notification. "You know what that was?" Kris said to me quietly. I said, "What was it?" He said, "I'll tell you later." I said, "What, an Ebay notification?" He died laughing, and said "Yeah!" Later, still about 15 meters underwater, he performed a pantomime of someone typing on a keyboard responding to Ebay bids. I knew exactly what he meant, and laughed/cried silently.
