<prompt> Human: A couple of years ago, my sister broke up with her boyfriend, and was left with around 6500 of credit card debt which she could not afford to pay off. At the time, my step mother and my sister had a bit of a shaky relationship, but she confided in her about the debt, telling her that she needed help but didnt want my father, or me, to know about it as she was ashamed.My step mother called me and told me about the situation, saying that she was only telling me because she could not afford to help her out, and that she didnt want to stress my father with it as he couldnt afford it either. I agreed to pay, by giving the money to my step mother, in order to keep my sister from knowing that I knew. The benefit of this was that it would help repair the relationship between my step mother and sister, which it really did.Fast forward to last month. My sister still doesnt know that I gave her the money, and I dont want to change that because its been really beneficial to her relationship with the family, but my step mother isnt pushing for her to pay it back either, meaning that Ive still got nothing back. Ive accepted this until now because neither my sister nor my step mother could afford to, but my step mother has come into some inheritance, roughly around 140,000 in cash, and has used about 15,000 of it to pay off a mortgage and some debts. Ive asked her to start paying me back what is owed, but she is refusing, saying that its my sister who owes me it. Am I in the right to ask this of her? The way I see it, I lent her the money, so that she could lend my sister the money. I know legally, theres not much that can be done, but Im being made feel like Im the greedy bad guy here, and Im interested in the opinions of others.  <response>: This is not a finance issue but your step mother is obviously wrong. She asked you for a loan so she is indebted to you, not your sister. Banks work the same way. They take out a loan from another bank to give to you; you pay more interest than they do because they are taking a risk on you.People are more greedy when they have money so feel free to call that shit out.
