Probably when the car i was in was involved in a crash. Basically, the guy in the van behind us was too busy trying to change CD in the player to notice our car slow down for traffic pulling out of a side road. He went into the back of our car at just under 60mph and managed to write off his own car. The rear of our car was pretty wrecked, luckily no-one was in the rear seats as the Police who came said if anyone had been in the back it could have been potentially fatal. No-one was seriously hurt, the guy who hit us was treated for shock and me and my Uncle, who was driving, were just a little shaken up. Another one, although not really terrifying but bloody painful, was when i was shot in the shoulder by some idiots with an air rifle on my way home through the park. One trip to A&E later, where the nurse removed the pellet without any anaesthetic (She said she had numbed my shoulder however, i felt everything) and it was probably the single most painful thing i've ever experienced.
