<prompt> Human: My little sister decided to tie the knot with a guy she met at college. The only problem is theyre poor college students. My parents said they would help out, but can bairly pay their own mortgage. So I decided to step in and help pay. The only problem is that my little sister doesnt understand how to save money and considers our family an endless piggy bank that she can always come back to when she is in a pinch. So I decided to now charge her like a bank would for a loan for this wedding so she can start to see how there is no such thing as a money tree and we really have been saving and working hard. Any suggestions?  <response>: Why cant your sister fiancee wait til they save up their own money before getting married?That to me sounds like a better way to teach her how to work hard and save.
