People in general.
Shitty drivers. Some guy in a truck crossed over from the right lane, right in front of me, to the far left lane this morning and all the traffic just had to stop.
I was at a ma**ive truck accident yesterday. there were pieces of the dude lying all over, we had to watch where we were walking and our photographer stepped on what we a**umed were brains cos there were bits of his skull lying close by.
