Has my nephew been living in my uncle's house?

1. My nephew is not my biological uncle's biological child, so there is no way to calculate the cost of living together. My uncle wants to live, and he doesn't charge you for living. He is nervous, you charge you for living expenses, but you say he is stingy.

If you are not a family, don't think about living together. Don't mention such embarrassing things. Everything must have a boundary, and so must relatives.
