I had an acquaintance, I hestitate to call him a friend because he was flat out crazy, his father had spent a lot of time institutionalized and it was in the genes. We were working in a place that fabricated steel works for bridges that was predominately black in location and workers. He made a crazy statement at work one day, that he was a card carrying member of the KKK, it didn't go over very well.
He bought a handgun and sequestered himself in his apartment (we were living in the same building) waiting for the N's to show up. They did but apparently he scared them off with threats about his gun. Later he ended up in an argument with his ex who was at the time sharing his apartment, he shot up the apartment and threatened to kill his ex. Later yet he shot himself 'by accident', for the 2nd time in his life.
There are many stories surrounding this guy, like the time he and his dad got into a Texas Death Match in the front of the apartment building in Wichita Kansas though His dad showed up dressed in several layers of clothes looking like he was going on Safari armed with a butcher knife. Dave defended himself with a large wrench, with a hysterical laugh he related how he had literally knocked his dad out of his shoes.
I could go on for hours. I was never so happy to dissociate from a raving lunatic.
