Why is it considered acceptable to be naked especially at the pool or beach?

If I were you I would forget about nakedness & instead concentrate on learning how to spell and construct a meaningful sentence. Once you have mastered those skills you could then work on developing a well-constructed argument. Based on your article above you have a lot of work in front of you. For example, naked means unclad (that is, people who have any clothes on at all are NOT NAKED)!
