According to Tom Junod:
A fight to the finish is what finishes a marriage. That’s because over the course of married life, people supply their spouses with precisely what’s required to finish them off. The question is not who can win, because anyone can win if they’re willing to go far enough — if they’re willing to win at the cost of love and respect. The question is who can abstain from winning, who can resist the temptation of winning, which, like any other marital temptation, is always there.
But how do you do that? Well, you don’t go to sleep angry, as the old saying goes. And you don’t say what can’t be unsaid. And you don’t fight drunk, because not only will you then say what can’t be unsaid; you will find out what it is.
A very wise man.
