A guy I knew from the 70s and did a lot of deals with was a narcissist and a pathological liar.....he had four wives that I knew of ,and was always cheating when he was married.....he also had a great aversion to paying his debts........never the less ,he had the gift of the gab ,and made a lot of money at times .......when I retired ,I let everyone go that owed me money,anyhoo,he paid me up to within $700 ,which meant I couldnt bankrupt him........then when he found Id written everything off,he wanted his money back.
