A number of months ago my wife and I had three couples over for dinner. They are aware that we lead a D/s lifestyle (it's no secret), but to them it's just about “whips and chains”. They have never asked for more information, and I have never volunteered it.
After dinner we were sitting around, and one of the women started a joke which was something along the lines of “What women need to know about men”. What followed was a set of man-bashing one liners that everyone (except myself and my wife) found very amusing.
Finally at the end I said, “Well, as far as I'm concerned, women only need to know one thing about men. Women have to do as they are told.” This was greeted by uproarious amounts of laughter, and when I said “No, I'm serious”, the level of laughter doubled. They could not get it into their heads that I was speaking seriously.
Life is strange that way at times.
