My mother is patriarchal, greedy and vain, and has crooked ideas. If everyone she contacts is crooked, reason with her and persuade her to treat you as a joke. What should I do to her?

Such people don't listen to advice and don't care as long as they don't do anything that violates the law and social morality. It is impossible to talk to others with such a personal character. People are divided into groups, as long as they are not cheated, they don't have to worry too much. Some people really haggle over every ounce, and love takes advantage of small things. This is not uncommon and normal. That generation is afraid of poverty, and it is normal that they will lose money if they don't take advantage. As long as you grasp the degree, you don't have to worry too much.
