Some people are like this. They can always take advantage of you, but you can't take advantage of him at all.
Take him a little. Everyone thinks you owe him a lot. This kind of person knows to take advantage of others and refuses to suffer a little loss.
Such people will not be liked anywhere. Since this is such a family, it is unnecessary to suggest not to associate with each other in the future.
It is really speechless to meet such relatives. Your cousin used to live at your place. Why didn't he fucking talk? I hope his family can talk in a few days.
It may be really inconvenient for her, but don't associate with such family members in the future, which will make you feel very uncomfortable. People who can't get in and out have nothing to get along with.
