A position of power,education,good upbringing,etc,means nothing in certain situations.
You can be an otherwise very polite,well spoken person who would do anything for anyone,but have the mouth of a truck driver(old saying.not meaning all truck drivers use vulgar words).
I know a man who retired as a corporate vice-president for a bank known round the world.
Women would leave the room when he got on a rant,but in a family or social setting, he was a perfect gentleman.
I have a work vocabulary(all men at work),and a social,family vocabulary. I'm positive there are many men AND women who have the same(Hilary was well known for her potty mouth toward others,including Secret Service personnel that would take a bullet for her).
Mountain out of a molehill! I'm sure there are plenty of past Presidents who used vulgar language behind closed doors. THEIR subordinates weren't petty enough to tattle. HilarysMouth
