OK, here goes.
Crappy TV adverts.
Darts players who look towards the camera like they've done something amazing. Mate, you've thrown pointy things at a BOARD, you haven't run the London Marathon!
People who don't indicate at roundabouts.
Reality TV contenders who try to use their appearance on a show as a short-cut to fame.
People who appear on X-Factor/Pop Idol with a sob story trying to get sympathy, and others who say it is their 'last chance' to do 'what they love' despite the fact that most recording artists have worked bloody hard to get where they are, another short-cut thing there.
People who speed up their car on their way to a junction, then brake sharply when they get there.
People who drop litter on the ground despite the fact there is a bin close to hand.
People who can't control their dogs, I can't think of the number of times when out running that I have nearly tripped over some bloody dog!
