I sit alone in the hall under a large stained glass window. I'm annoyed because the poltergeist Peeves, who had been annoying me for about ten minutes, stopped shouting vulgar rhymes and leaving me finally alone. I sense your presence even when you try to hide in hope that I will not notice you. But my other senses are much more developed. And I have a magic wand, which I took out of my pocket to make sure that I'm not imagining things. I don’t know who you are, but go away, I said loudly.
