Daughter-in-law wants money to buy a car, how to persuade?

You settle accounts with her, all the big expenses since you got married, and then talk to her about the expenses of children's future education and the situation of your parents' home, so that she can judge for herself whether she has the money to buy a car, so that you can say that you keep all the money at home, and you don't know if you have any money? You must let her know that your parents have no money. People like this who only think for themselves are mostly only children. Anyway, there is no money in a word, no matter how she makes trouble, you are right.
