Insanity

Is it ever 'right' to be rude to a person that continually just doesn't "get it"??? Where is the line between getting your point across in a tactful manner and just getting the point across??? Time and time again, I am amazed when a particular person refuses to hear what I am saying. I say the same thing over and over and it is as if they expect the response to change if only they ask the question 'one more time'. I am reminded of a saying that I once heard on a movie... "Insanity is repeating a particular action over and over and hoping that the outcome will change."

I think I have an insane person in my life and they are driving me bonkers!!!! Unfortunately, I cannot remove them from my life, only distance myself.
