Why Insults Hurt—And Why They Shouldn't | TIME.com
My observational experience leads me to believe that if someone tries his or her utmost to insult me directly or indirectly by words or actions what I do is just keep silent or do nothing or put an impression (if possible) as if I seldom notice or pay importance to such stupid talks.
Otherwise, I could respond with a heavier coin but that results to a quarrel or a fight, whereas, I know one who is habituate to insult the others is understood more often a mean fellow. His or her meanness can harm him or her (far more than what it could do to me) to an extent that he or she may be ruined ultimately. So, what I do is for his or her welfare, I mean, I don't respond to his or her insult to benefit him or her, not me. As a result, I'm the winner, whereas, he or she is the loser.
