What if she doesn't like cooking for her mother-in-law?

You don't have to worry about that yourself. She said it wasn't delicious, and she cooked it herself. You think your cooking is delicious enough. Families have different habits. Let's respect each other. My mother-in-law and father-in-law came to live with us. That's what she said. The food I cooked is not delicious. She likes cooking. It is delicious. I will eat more. If it's not to your taste, make some yourself or go out to buy something to eat. Say it in advance, your eating habits will be different, and you will be fine. Everyone has hands and feet, can move, and no one has to wait on anyone. Only when women are economically independent can they have the right to control and speak in life.
