I know that some people (or at least Ann Landers and Dear Abby) think it is extremely rude to wear a hat indoors and/or in restaurants. I also know that many people take off their hats during the national anthem. I also think that hats are sometimes taboo in church, but I may be wrong on that one since I have not spent very much time in a church.
I don’t get it. What’s rude about a hat? What’s respectful about not wearing a hat? Why not socks? Why not belts? What am I missing?
