What should I do if I have great obstacles in communicating with my parents?

The generation gap with parents is more than a little. I have lived with my mother for several years in recent years and found many problems. The first is the concept of spending money. Some people in the older generation are frugal, even a little too much. You can't spend it here, and you shouldn't buy that. To tell the truth, the quality of life is much worse when the old man comes. In fact, everyone knows that she is also good for us. But now the young people's idea is that the quality of life should be improved, and it is necessary to go out for dinner occasionally. This is the most difficult problem to communicate. Old people have another problem. They think the refrigerator is omnipotent. The meat in the refrigerator should be kept at the end of the year. You can't throw it away. I can fight you if I lose. I have no choice but to listen to her. If I do, I will tell the child not to eat, and accompany her to eat. If you buy carrots and vegetables for a week until the leaves are rotten, you can't talk, but you get angry when you talk. If you lose them, you say they are a waste. What should I do? If life can shield him like a mobile phone, I think. But it's my parents after all. When I was very young, I saw my parents complaining about my grandmother: things were not packed well, and the house was full of colorful plastic bags. Today, I saw my parents making the same mistakes as my grandmother. I can only say that when people get old, there will be many problems, such as poor memory and slow action. I will be old one day. What should I do? Accept it. Accept their old age as they accept our youth and irrationality. Now, my parents put plastic bags in the corner of the house, so I pick them up and throw them away. We can only understand each other!
