Harry Potter

When you say you want to go to Hogwarts, your father immediately has a fit, "I knew having a daughter would only lead to uselessness. I should've known a girl could never carry on my..." But you and Hagrid were already out the door. For the night, he lets you stay in a cabin about 40 miles from your house just to be sure there isn't any stress for your first day at the academy. The next day, you wake up bright and early to get started on your day. Hagrid rushes you down Diagon Alley, picking up school supplies along the way. You are late for your first day. Hagrid must leave you, so you are completely lost trying to figure out where the train platform is. You do the calculations of where 3/4 is and feel the wall there. Solid. You take a deep breath. You are probably wrong and are going to whack into the wall, but for some reason, you are feeling brave today. You are relieved to find that by some miracle, you were right. Now you run to catch the train. There are five cabins with spaces left. Draco Malfoy, Crab, and Goyle sit in one cabin. Neville, Ginny, and Luna sit in a cabin. Harry, Ron, and Hermione, freshly introduced, sit in a cabin. And then there is an empty cabin. Where will you sit?
