You know when a pedestrian crosses in front of your car when they really don't have much time to do so (because you're driving towards that bit of road!), but instead of hurrying across, they strut/meander as if they have all the time in the world? I'm talking about teenagers usually, who seem to me to be doing this with "attitude" and just expect me to slow down/stop until they've ambled across.
Well, I've started spraying them with my windscreen wash.
AIBU?
