You suddenly feel yourself frozen in time, or though it seems, as you quickly fall to the ground. With a loud "thunk", and a small "swoosh", you feel your bones being crushed with the impact of the fall. But what you thought was a broken bone was just a very badly sprained wrist. Being one to be able to put up with pain you miraculously stand up and study your surroundings.
You take a step and feel your shoes slip on the moss covered rotting tiles of the roof. As you slowly build up speed in your descent to the ground your shirt gets caught on the nail. Of course the nail does nothing to stop you from falling, it just rips the shirt that your mother bought you (but you don't like it anyways)
