it was late at night and you were sneaking around Hogwarts, you finally made your way to the library, you snuck in the restricted section and started flipping through book until your find this old black book the had "Tom Marvolo Riddle" engraved in the front of it, you opened it and it was empty. You sat down on a desk, looking around to make sure no one was there and then you opened the book to the first page. You reached for a quill and wrote "hello" just then.(You make it up from there :))
