When we were at DL last week, we happened by the flag retreat ceremony. When the flag was lowered, the band played the Star Spangled Banner. Everyone stood and either sang or were quietly respectful. Except for two young men (upper 20's?) who remained seated, with their hats on, looking totally bored. I was raised to believe that you always stand for the National Anthem (unless you physically can't) and behave appropriately. Has this gone "out of fashion" or something, or was this just total rudeness?
