<prompt> Human: Unfortunately my younger sister22yo got a bad leg injury in January that required a total of 3 surgeries. My parents are footing the bill but I think they are spread thin financially and my dad is only a year or two away from retirement.I want to help out my parents because I know how stressed they are about it. I am afraid that they wont accept my money if I offer it because my parents are proud and they think I should be saving my money to buy a house. This is why I would like to know how to anonymously pay part of my parents bill.  <response>: Contact the hospitaldoctors office that generated the bill and ask them if theyd be willing to keep it to themselves who paid off the bill.
