Most of these demands for "clear definitions" are childish. They are made by people incapable of judgment. They want "Daddy Matt" to tell them what they can and can't do. (How come I have to be in by 10? All my friends can stay out 'til 11.) In my opinion, they'd do better if they worried less about their "rights" and more about the rights of others.
You've already said it, Matt. "It takes common sense to deal with these issues."
