Can I tell my brother he needs to get better at gift giving?
Why would you want to tell your brother that?
I keeps paying his bills, he never seems to give me gifts either.
It is rather rude to demand a gift from someone if they are poor. You should do favors for people without expecting anything in return.
It's my family's fault that they are poor, they should have stopped spending time on my nephews.
Giving is a selfless act and expecting something in return ruins the whole concept. While it may stink to not receive the gift you wanted, your brother still took the time to get you something, so try to appreciate their thoughtfulness at least.
