On etiquette.

I am admittedly not up to speed on the finer points of etiquette and, most likely, I come across as a jerk a lot of the time.

But at what point are you allowed to hurl obscenities at the homeless guy who just sprayed vinegar and hobo juice on the car that the day before you spent an hour washing by hand? Seriously, I thought they stopped trying that act in 80s movies. Thank god it rained that night to help wash some of it off. I just worry I was too hostile to him - OR NOT HOSTILE ENOUGH.
