Mother-in-law won't listen, will you talk back?

Girls will become other people's daughters-in-law one day. I told my mother that I would be a good daughter-in-law after marriage and I would be good to them. But my mother told me that your original intention must be good, but it doesn't necessarily mean that your good will be exchanged for others' good, which means that you can't make concessions without principle! Therefore, I think what my mother-in-law said, if it doesn't bear listening and doesn't violate my bottom line, I won't contradict it!

For example, my mother-in-law said that I spent too much money or my little habits were not good enough for me to correct, or I said that there was something wrong with my life, so I shouldn't refute her face to face. After all, I am an elder, so it is appropriate to say my children. It's all irrelevant. My concession doesn't mean I'm afraid of my weakness, just because I love my husband, so I want to reassure him. I don't want to cause him unnecessary trouble, and I don't want to be an unfilial daughter-in-law!

In another case, I will talk back to her. For example, she slandered my personality and didn't respect me, or I was from a poor family, so I wouldn't give in. Once upon a time, there was a neighbor whose daughter-in-law quarreled with her son. Her mother-in-law only defended her son and scolded her daughter-in-law: Your family is the same. I can tell what kind of people you are at a glance! Married to our family, your ancestors burned incense! As far as I know, the daughter-in-law is only in a bad financial situation at home, and her personality is nothing serious. As her mother-in-law, I have to say that she has gone too far. If I were you, I would definitely talk back to her in this case, otherwise the bottomless concession would only make her worse!

This kind of thing must have principles, but it can't be tolerated at all!
