The differences between Europeans and USns is much like the difference between city dwellers and country folk. Country boys know everybody in town, and know that their reputation will suffer if they are disagreeable. City boys know only the people in the neighborhood, and don't give a damn about anyone outside it. They get used to hostility from the outsiders, and pride themselves on being 'street wise" with a full repertoire of insults to repay insults received, and vastly superior to us country boys.
