Coming off one of my lawns today, I see three teenagers walking by my truck, one takes a little to close of a look inside of my truck, window down, and one of others spits inside. I saw the first kid and was a little angry, then the spitter sets me off. So I pull my mower right infront of the kid that spit in my truck who was riding a bicycle and went off. I definintely had some pretty choice four letter words to say and out came "Clean my f-in truck off now". So over he went and cleaned the side off with his shirt. I told him I was making it a point that he wouldn't forget so he'd never do it again. Hopefully this will stick in all 3 of their minds and will be a reminder next time they think of doing something like this again.
