Wikipedia relates an interesting History of the Baseball Cap (https://en.wikipedia.org/wiki/Baseball_cap). My question/concern is why do adult males wear them, when not playing a sport or part of an official uniform? Of particular concern is why men wear them year around, in all seasons, in all kinds of weather? Surely they do not keep one warm in cold weather. I also understand elderly veterans displaying their war or unit proudly on their caps. I also understand wearing caps with political statements. What about the others? What about wearing the cap backwards? Do they realize this started in prisons! What I really do not understand is why anyone wears a cap indoors, in particular in restaurants? I have often seen three generations of males at a table with all wearing caps while eating. I am past 79 years old and perhaps reflect my parent's injunction against wearing a hat indoors. I also spent three years in the U. S. Marine Corps where you took your cover (cap) off when entering any structure! A story still sticks in my mind. While in recruit training at Parris Island a recruit in front of me failed to take off his cover quick enough when entering the mess hall. Well, the drill instructor jumped all over him and made him eat his entire meal out of his cover. Lesson learned! Appreciate all non-political comments.
