The first one to find unicorn hair in the room would win, so you started to search running, but Draco found some unicorn hair on the floor next to a bookshelf. You looked at him, waiting to know what the punishment would be for losing the bet "You will have to hide under Professor Snape's desk for the entire class, and be careful not to get caught by him" Draco says laughing. You open your eyes in surprise, but you have no choice but to accept your fate. You approach the desk and get under it, sitting there. Your friends sit at their desks, holding back their laughter and waiting for the classroom to fill up with the other students and the teacher
