Before you argue with someone, ask yourself, is that person even mentally mature enough to grasp the concept of different perspectives? Because if not, there’s absolutely no point. – Amber Veal
Discussion is an exchange of knowledge, argument an exchange of ignorance.
I think the biggest mistake I made was this wretched ability to see both sides of an argument.
The most important thing in an argument, next to being right, is to leave an escape hatch for your opponent, so that he can gracefully swing over to your side without too much apparent loss of face.
Argument is between two sides or individuals, never say silly to your friend because he/she never argue on oneself.
