Tact is the ability to tell someone to go to hell in such a way that they look forward to the trip. – Winston Churchill
Sure, this quote is dripping with sarcasm and is both clever and funny, but it raises an important point (by way of absurdity . . . ):
How tactful are you?
Could you tell someone to go to hell, and they would look forward to the trip?
Maybe not, but how close could you come?
