I have no trouble tailoring my speech to suit the circumstances viz a viz the decorum a given context demands or the sensibilities of those present, but relaxing with friends, talking about certain things, maybe on the outside of a grog or two, I have been known to swear like a trooper, as have the friends I hang out with. It all stops if a stranger sits down with us, until... they turn out to have a potty mouth too, and everyone reverts.
Do you use much profanity?
I use it to express a certain point with close friends or family and I always prefix one particular president’s name with the F word in conversations.
