During the Spring Festival, my brother went to visit my in-laws.

This is definitely the time to reflect women's wisdom:

Since you call your in-laws "dad" and "mom", you have to treat your in-laws as parents! . If this conversation is your parents, do you think they are right? You may even laugh at your brother: "Yes, stupid, not tired?" It's over.

The problem now is: you treat your in-laws as outsiders, and the courtesy of outsiders requires them … If it's over, you'll have a big problem! Because your resentment is accumulated bit by bit, and it will eventually erupt.
