Do you mind if your mother-in-law invites her daughter over for dinner every three days?

It depends. If my mother-in-law is a simple, enthusiastic person who doesn't have much to do, and both families live not far away, very close, and she only needs to open her mouth every time she eats, and she doesn't need to carry anything in her hand, then I won't mind. After all, some daughters get along well with their mothers and live near each other. Naturally, they want to ask their daughters to stay for a while and then have dinner together, so the relationship between mother and daughter must be very good, just a meal, so there should be no need to mind. Of course, if her mother is that kind of thing, try to provoke the relationship between you two after dinner and make you both angry or something. Or it is not necessary to buy something empty-handed every time. After all, it doesn't make sense for us to go back to our parents' house at both ends. So it depends. If there are no other circumstances, then it is no problem to eat according to your own daughter. Isn't it time-saving? How nice it is not to buy food and disturb!
