Hogwarts

You blew the cake you drew in the dirty floor "happy birthday to me." you whispered quietly to yourself, suddenly you hear a boom, you jump slightly, Dudley sits up quickly in panic "wheres the cannon!?" he asks stupidly, uncle Vernon and aunt Petunia came down the stairs, the door fell onto the floor and a giant man walked into the shack, he picked up the door and put it back in place. "Sorry bout that, I'm Hagrid." he said simply with a rough voice.
