My mother is a little abnormal now. Every day, she thinks that there are no good people in the world and keeps speaking ill of others outside. I am embarrassed and don't know what to do.

This man, a bit like my grandfather, should be said to be insecure and lonely at heart, and should be the kind of leader who was always used to it when he was young. He should also be the kind of stubborn and paranoid person who always feels that he is right, selfish and self-centered. For such a person, it is impossible to treat him as a child, but ignore him. He is as self-centered as an old fogey. Whenever something goes wrong, he talks nonsense to outsiders. Every time he praises himself, he always says that his children are not good. Some things are clearly your own fault, and it can be said that black is white. It is really a headache to put the blame on others and think only of yourself. The solution is to follow him if he can promise. If it is really unreasonable, he will let himself make enough trouble, and no one will pay attention to him or ignore him. The key to making trouble is not to let anyone provoke him in it and let everyone ignore him. If he gets bored, he will stop making trouble. This is that the older you get, the more noisy and unreasonable you will be like a child. Children can only endure it first.
