On Maintaining Your Beliefs
If someone says to you, "I think your behavior is shameful.  You say, "well, thank you, I appreciate you sharing your opinion."
  Then if they say, "I think that what you believe is stupid and you are wrong and who do you think you are and you are selfish and you are certainly not going to get my approval"
You say, "Thank you for your opinion, it helps me concentrate.  I particularly like the way that cockroach walked around your coffee mug while you were talking about MY LIFE.  And what threw me into a state of absolute ecstasy was when the cockroach stopped, looked up at me, winked, and then urinated in your coffee.
I love it.  I totally love it."
