My mother-in-law is talking nonsense.

This is the difference in the generation gap era. The most important thing is that she also came from a young wife. As the daughter-in-law of their time, she suffered a lot and suffered a lot. I feel that what she suffered when she was a daughter-in-law should be borne by someone now. This is a psychological imbalance. It's better to talk to her openly if you have time.
