When self-esteem is hurt, it is not always possible to be generous. If you ignore boorish behavior, and resentment and indignation do not leave, you should learn to adequately respond.
People who are poorly educated and unsure of themselves are prone to rudeness. Sometimes tactful remarks, appeals to calmness and reasonable arguments do not lead to a positive result, but only warm up the "righteous" anger of the interlocutor. Such situations force you to learn to put the boors in place, but you need to do this skillfully, beautifully!
Confused
With any daring communication, a scandalous person initially considers himself superior to his opponent or wants to prove it to himself. Perhaps a certain status does allow such behavior, at least in its understanding. Plus, there is an energy discharge - its own unresolved problems are shifted to a weaker one. The purpose of rudeness is to unbalance, hurt the living and exalt oneself in one’s eyes, so it’s worth reacting calmly, with a share of sympathy and, if possible, with humor. Sincere or feigned empathy can lead to complete confusion, because louts seek to gain confidence and power, but not pity and understanding. With humor, angry people are even more complicated. In fact, they take the whole situation seriously and are committed to the further development of the conflict. In response to an ironic remark: “And then Ostap suffered” or a remark: “played badly, ” I don’t believe it! ”A real embarrassment can occur. All previous abuse was perceived as an unsuccessful joke, bad acting work. There is nothing left to do to turn the conversation into normal channel or abandon further communication.
