Why prove to a man he is wrong? Is that going to make him like you? Why not let him save his face? He didn’t ask for your opinion. He didn’t want it. Why argue with him? Always avoid the acute angle. There is only one way to get the best of an argument-and that is to avoid it. Nine times out of ten, an argument ends with each of the contestants more firmly convinced than ever that he is absolutely right. You can’t win an argument. You can’t because if you lose it, you lose it; and if you win it, you lose it. So you have proven another man wrong. Then what? You will feel fine. But what about him? You have made him feel inferior. You have hurt his pride. He will resent your triumph.
“If you argue and rankle and contradict, you may achieve a victory sometimes; but it will be an empty victory because you will never get your opponent’s good will.
