The skateboarder

On my way through downtown, I spot a skateboarder in the lane ahead of me. Seeing as I had quite a bit of extra time I decide to slow down and let this guy cruise (ride? skate? I'm not sure of the correct terminology) along. Glancing behind him he notices me and moves over so I can pass him. Making eye contact, I wave thanks at him. As I pull up beside him he then gives me the finger. Heh? Where did that come from? "Cunt! Dyke! Bitch! Lesbian! Go to hell you nazi bus driver!" He yells at me. I respond by closing the window. This guy's anger towards me is wholly misplaced. I could have been a dick and honked at him to move but I didn't. I decided to be nice and he responds with hatred. It's these sort of situations that baffle me. You give someone kindness and they throw it back in your face.
