My mother-in-law said my father-in-law was rubbish, and he didn't say a word when he was there?

Hello, you'd better stay out of this situation.

First, my father-in-law loves her mother-in-law, and her mother-in-law scolds her father-in-law. My father-in-law is patient and doesn't care about her, as long as she is happy. Of course, my father-in-law said nothing.

Second, my mother-in-law is used to bullying, and my father-in-law can't mess with her. She has been bullied since she got married, and she is used to being bullied. This is also natural.

Third, my father-in-law is generous and doesn't care about such a trivial matter. He doesn't say a word or refute it. He doesn't want to destroy everyone's goodwill because of such a trivial matter, nor does he want to show family disharmony in front of his daughter-in-law.
