There is this TV commercial I've seen several times lately. Some guy opens the hood (bonnet) of his car to change his oil. He finds a little man (dressed in car racing outfit) standing on top of his engine. The little man explains the benefit of a particular kind of motor oil.
The regular size man asks the little man, “May I ask you a question? Why are you 3 inches tall?”
The little man turns it around and asks, “Why aren't you 3 inches tall?” (That is a very good question.)
I think that's the attitude I've developed about being naked. When I see prudish people with fabric covering their bodies I wonder, “why are you all covered up.” I wonder the same question about Muslim full body covers and Christian middle body covers. Why is your beautiful human body all covered up in ugly uncomfortable unhealthy fabric?
That is the real question. It is not “Why are we naked.” The harder question is, “Why aren't you (others) naked?”
