Pricks that don't indicate when turning, especially when i'm on my paper round (need to find a job, no motivation lol) and someone is coming speeding down a road and i cross over a road leading off it, and the person isn't indicating, so i think they're going to carry on, but turn down the road! (wankers)
and people reversing off their drives without looking (and crashing into me and having a go for marking her car, so i called her a biatch and rode away)
