It was a used disposable diaper. Someone had dropped their kid's fucking shitbag into my truck. It was sopping wet, so I have to assume that they did it before the morning rain, sometime Monday. I had to pick the goddamned thing up with my hands and put it in the trash.
I don't understand why my truck has become both a yard sale and a garbage can for the people who live in the projects behind my house. I just know that if I ever find out who did it, I'm going to light them on fire with gasoline and watch them die. And then I'm going to steal their child and raise it to spit on his mother's grave and hate everything about poor people, just to appease my schadenfreude.
