WWII ended a few years before I was born. However, I remember by dear, sweet Mother telling me about how much nicer and kinder the men were "back in the day." My Dad was at war, so my Mom did her part serving in the USO and going to dances to dance with GI's coming home or on leave and had to go back. She said that a few hit on her, but mostly they were gentlemen and bad language was never tolerated. She told me that very seldom did she ever hear a cuss word and never an "F" bomb. I don't know if movies in that era had certain rules for swearing or not, but I can't remember ever watching a film from that era and maybe not before the 60's until I started to hear the cussing. Last night, I watched Tora! Tora! Tora! for the umpteenth time and I can't recall if anyone swore or not. If they did, it may have been only a very few less foul words.
