I used to have a memory like a steel trap and now between the narcotic pain killers I take and the age it is more like a putty trap these days.
A few years ago a friend came over and handed me $300.00 and said thanks and I was like "What is this for?" and he said "The money you loaned me" well I was in a hurting way money wise and I knew he knew it and I thought he was just trying to help me so we wound up in an hour long argument about whether he owed me money or not until he finally got it through my thick skull that he really was right, he really did owe me the money and was not just being charitable I had finally remembered when I loaned it to him! Needless to say he is a friend that I have kept around!
