arguments you won't win

Have you ever been blind-sided by a "conversation" that comes across as a directed phrase, with an overtone of argument? It's one of those where you are damned if you do or damned if you don't... respond to the "statement". I already know I'm doomed, so why fight it. No matter what I say (or don't say), the tone will be wrong, or there will be some type of attitude attached.  No matter what, I am wrong, she is right, and that is that! And I know, that if I were to say what I want to say... I might as well write my life off now!
