<prompt> Human: Two years ago I gave a loan of 15k to a friend who was having financial problems. He has made some payments but has barely put a dent in the loan. He has agreed to pay me back the full some plus interest. However I can no longer trust him as he intentionally ignores my calls. I was hoping all of you could help me in finding an applicable contract or something of the sort that will legally bind him to repaying me within a realistic time period. His negligence is seriously affecting my life. PLEASE HELP!!  <response>: Doesnt sound like you got anything in writing beforehand so you dont really have much legal options.
