My wife Ruby has a friend who has a bit of a problem with her husband. My wife's friend is an educated woman who has to attend many "high class" social events and her husband always loves to accompany to the events. However, her husband is a redneck country boy with a big ol' mouth. He likes to tell off color jokes that would fly at your local honky tonk but do not during a high class event. Then he'll use colorful language when talking about sports and slapping people on the back.
So how does she tell her husband how to calm it down without hurting his feelings. Because in his walk of life those type of conversation are fine. She is looking for advice on how to teach her husband some ettiquette without making him feel degraded.
