Some of the stuff we teach our kids in the south is a bit silly to me. We teach them to respect their teachers and coaches, if a teacher or coach talked to me now, the way they did when I was a kid...there would be some punches thrown.
We teach them not to wear hats indoors. That had no application to my adult life.
We teach them not to curse. Then we all grow up and most of us curse regularly. My sister had a foul mouth for many years but now that she has kids she scolds me for using even the tamest curse words. It's all a bit silly to me but I go along with it.
Every time you wear your hat during the national anthem, Jesus sends George Washington to hell for a week.
