To begin with, you need to understand what causes such a non -standard reaction, maybe a person releases a mockery, in principle, is not able to normally conduct a dialogue or perhaps in such a non -standard way he strives to draw your attention to his person. In addition, there are people who know about their mistakes and misses, try to hide them from others thanks to criticism of another person. Typically, such people are not of the highest opinion of anyone and just at the moment under the object of ridicule or criticism is a particular person. In such a situation, you just need to learn to clearly and directly say about the person with his own weapon, he criticizes the behavior manner, you need to point out that hour to his loud laughter, at the meeting or ask him a counter question about how he sees really correct behavior.
