My brother likes to speak ill of me in front of my mother. Some are facts, while others are made out of nothing. What should I do?

Whispering behind the scenes, this kind of thing has actually been done by children. I don't think it matters once in a while. Just say a few words to guide you However, if your brother has long formed the habit of speaking ill of his family behind his back, it is his bad character. The reason why he has a bad personality is that he is at your mother's house. Complain. Got the cone he wanted. So he thinks this method is effective, so he will implement it again and again. The root cause is your mother's education. You should say it directly in front of your mother. Of course, you should also consider it from your mother's point of view. He may think that your brother is still young, or that your brother is a boy, so you should give her more. But you have to stand on your mother's side. Since she loves your brother more than you, in this case, he hopes your brother can grow up better and better. You'd better analyze what consequences your brother's current behavior will have on her future. This will attract your mother's attention and let your mother guide your brother correctly. Because children are very malleable, if your brother had a hard time complaining to your mother for the first time and felt that this kind of thing could not be implemented, she would not implement it again. Children's animality is sufficient, and it is theirs to seek advantages and avoid disadvantages. The source of all actions. So he can get rid of this problem as long as he cuts off the benefits and roots of this behavior.
