Children always borrow other people's things, but never come back, so let him continue to borrow?

Ask the child if he lent something to others or gave it to others. If you give it to someone else, your parents will never get it back. You think what he gives to others, if parents ask for it, will cause a serious blow to the child's self-esteem. Children are a kind of loyal psychology, they will think that they have no face and may have conflicts with their parents. If you really lend it to others, you should make it clear to him that the things at home may be for your own use. Even if you don't use it temporarily, you can't always lend it to others. Once you lend it to others and can't get it back, you will have to pay again when you need it at home at some point in the future, which will bring economic burden to your family. Make it clear to your children that you can't simply tell them: you can't do this, and you are not allowed to lend things to others. If the child ignores his parents and still goes his own way, there is no choice but to follow him and borrow it if necessary.
