Upstairs to the first floor! I climb on to the windowsill with an umbrella, open it up, take a quick look down, and before I have time to be afraid I jump. I land on a soft flower-bed and am surprised to find that I have twisted every muscle and actually broken a leg. In the tricky way in which umbrellas are apt to behave, the thing has turned inside out and hardly broke my fall. But nevertheless I abide by my resolve: I will be an airman.
