I have in the past struggled to get by and have asked her for a loan which she has always refused saying that she isn't made of money. Today I've found out that my brother has managed to rack up several debts that my sister has paid off for him and she says she doesn't want him to repay her. The amount she has paid off for is far larger than anything I have ever asked to borrow. I know its her money and she can spend it how she likes but I feel quite upset about this.
