What should I say when I get up in the morning and see my mother-in-law?

Friend, at first, you can ask your mother-in-law: "What to eat early, you can do it" or "You can buy it early". The key is to shout "Mom", so that she will be happy, she will run very fast, make breakfast or go out to buy breakfast or something, and when she gets used to it later, she won't have to be so polite.
