How do grandparents and grandchildren get along with each other?

I can only say that this is not an effective method that can be said in one or two sentences. I can only tell you what I know.

Do not quarrel, especially within families. Don't be rude (give others a bad look), as this will only alienate the relationship between your loved ones.

This is actually a two-sided matter, but now from one side, I can only tell you: Tolerance is great, you must learn to forgive and learn to be considerate. If it is really difficult to do, then just keep it out of sight. After all, distance can eliminate a lot of resentment. If it still doesn't work, then learn to be silent, or divert your energy and let yourself become a study madman or something like that.

Also, there is a method that is absolutely useful, that is, read more books (definitely not textbooks), read world famous books, and read ancient and modern history. As for why it is useful, I think you will understand it after many years. After all, a 13-year-old cannot carry too much.
