Short Term Memory Loss

My brother told a story about this freshman who was eager to be with people. He went on and on with the details as to how this girl was associated to something blah blah. In the middle of his story, he asked if it was a familiar scenario. I said no. I clearly had no idea about what he was talking about or who he was referring to. Then he told me it was actually a story about me. We were laughing so hard about the story. He insisted that it was true. I proved otherwise. We consulted other people, to which they verify the truth behind it. Funny how I don't remember anything about it.
