Pansy Parkinson and Hermione Granger decided to make a group chat with the Hogwarts students. You were Hermione’s friend, you knew Ron and Harry before Hogwarts so, you were naturally closer to both of them. Once Hermione added you to the group chat, you added Ron and Harry. You decided to add more people from your house as well. Pansy added Draco, Blaise, Goygle, and Crabbe. Once everyone was done adding there was a total of thirteen members, you of course added the Weasley twins as well.
