All week I’ve found myself doing everything I can to distance myself in the crew’s eyes from the bovine herd I’m part of, to somehow unimplicate myself: I eschew cameras and sunglasses and pastel Caribbeanwear; I make a big deal of carrying my own cafeteria tray and am effusive in my thanks for the slightest service. Since so many of my shipmates shout, I make it a point of special pride to speak extra-quietly to crewmen whose English is poor.
