Dude was talking shit behind my back in certain company because he was trying to gain popularity where he worked (I had a few enemies there). I also had some friends there, who heard it and brought it back to me. I don't give people a second chance where loyalty is concerned. Never spoke again face to face, and never ran into one another for years even though we lived in the same town. He knew I was going to knock him the fuck out if I saw him....so he tucked his tail between his legs and avoided anywhere I was likely to be for years.
Funny thing: Almost 8 years later, he lobs me a half-assed apology on Facebook and wants to 'make things right'. Are you kidding me?
