My friend Todd owes me a dollar. He has owed it to me for twelve months, and I fear there is little prospect of his ever returning it. I can realize whenever I meet him that he has forgotten that he owes me a dollar. He meets me in the same frank friendly way as always. My dollar has clean gone out of his mind. I see that I shall never get it back. On the other hand I know that I shall remember all my life that Todd owes me a dollar. It will make no difference, I trust, to our friendship, but I shall never be able to forget it. I don't know how it is with other people; but if any man borrows a dollar from me I carry the recollection of it to the grave.
