A Family Gem

My family has a LOT of sayings that we've used time and time again through the years, but of course, you have to repeat them often in order to preserve them, otherwise they might get lost by the brain trust (translation: the people who carry our genes). I can safely say that most of the good ones are firmly entrenched.
I was reminded of an all-time favorite recently.
Don't go away mad. Just go away.
To be used at the end of a disagreement to punctuate your "rightness", to the asshole who had the nerve to question it in the first place, and as a result, deserves this perfect dismissal.
The depth of the wound increases in direct proportion to the amount of flippancy with which you deliver the line, a sing song-y voice being the one that cuts the deepest, and therefore, affords the most pleasure. And who doesn't love that?
