(You were stopped at traffic lights in your brand new car to meet your friends at the movies when suddenly you hear a loud bang from behind, causing the car to lurch forward slighly. Looking in the mirror, you see a biker boy stand up and start stumbling about. He looks to be in serious pain, but he stumbles up to window, and you roll it down)

"What the hell was that for?!" He shouted aggressively, being muffled by his helmet. He sounded really shook up from hitting your stationary car at around 30mph. He stumbled, fell and you could see he was bleeding slightly from his leg. His bike wasn't much better. It lay, bashed at the front, with a long scratch down the side.
