people
beat me too it....
90% of people just piss me the fuck of, on account of their being total donkeyhonkers.......so I'd have to say people are wot make me wanna climb high builldings with a .50 BMG and a yard of scope...
...esp those whose drive Audis and BMW's.
Don't know why, but they are in my observation the most arrogant drivers on the road, bar none.
