My seventh grade home room teacher (1972 ish) was Mr. Davidson. He was one of many WWII vets who through the GI bill became teachers. We would stand for the national anthem when the announcement came over the intercom. One kid Jeff, decided he wasn’t going to stand and instead laid across a couple chairs. Mr. D came over and kicked his legs, told him in the war if a guy did that he would have shot him. No one saw a thing.
