I couldn't even believe it was possible for a human being to act in such a way. I knew I had upset him unintentionally, but I still couldn't believe. Yet the yellow stain on my brand new couch was very clearly a urine stain, and it couldn't have come from anyone else. It was no accident either.
It was from an ex friend of mine, who had mistakenly thought that I had cheated him out of a job. No matter what I did he wouldn't believe that I didn't do it. The day he had come over acting overly nice, I knew something was up. It was just hard to figure out until he got up and ran from the apartment, leaving the pee stain on my new couch.
