A man who publishes his letters becomes a nudist--nothing shields him from the world's gaze except his bare skin. A writer, writing away, can always fix himself up to make himself more presentable, but a man who has written a letter is stuck with it for all time.
I'm a nudist at heart.
I've been to nudist beaches, like twice.
But honestly, I just don't want to see these people naked. Most people look better with their clothes on, and the few that don't, look better than you, so why bother?
