On this subject.....I think that it is ;very important to, first......Know Thy Audience!
this leaves it to us, first, to make a judgement before speaking......
"Read" the other person/persons.....
And, if you can't read them, or you haven't had enough opportunity to get to know them....always err on the side of caution.....lol!
I think of it like...If you were the comedian who is asked to entertain at the Annual Press Dinner at the White House.....you would not tell the same jokes as you would at a private club, like Second City......
