What if I don't like my in-laws and relatives?

Vulgarity is an inevitable experience in life, and things you didn't like as a child can be escaped. When you grow up, you have to pretend to accept what you don't like. This is called superficial kung fu, also called society. When you marry your husband and start your own family, of course, you won't see his relatives all the time. You only met them on vacation. You can take part in accidental amusement if you don't like it. Be polite. Don't let people say behind your back that you don't know the gist. If you have to see each other all the time, you can explain to your husband and move out of that place. If you can't move out, then accept it calmly and don't make friends at ordinary times.
