<prompt> Human: Doing some 12 step work and got to number 9 about making amends. I remembered that 38 years ago a friend loaned me several hundred dollars that i never paid back. I want to do that now - should I include interest? How would i figure the amount?  <response>: If it is an actual friend, I would probably just slip an extra 100 in there for the inconvenience and thanks.
