I am her daughter, guardian/conservator. Mom still knows who everyone is but memory is very bad. Grand daughter 45 is coming over monthly and borrowing money. My adult nephew lives with her and assumes she pays her back but we don't know how much she is borrowing. He marks the calendar when she borrows the money and marks it when she supposedly brings it back. I am getting very concerned, should I confront the niece? I don't know if she is really paying her back or not. I don't live with her. I know how grandparents are about their grandchildren but I think this is becoming a habit.
