<prompt> Human: I borrowed 500 from a friend over a decade ago. I actually forgot about it until recently. I want to pay her back. Its obviously not fair to give her 500 now since it wouldnt be worth the 500 she loaned me at the time. My question is this: should I simply pay her 500 inflation? Or should I pay her something like the average return of the SP since she gave me the loan? What would you do?  <response>: If she does not expect to be paid interest, I would consider taking her out on an expensive treat which she would like best restaurant in town? and give her the 500. Or, give her the 500 in a card attached to an expensive gift you know she will like case of champagne?Good luck.
