Chapter 3-2 Aunt Marge's Big Mistake

• At breakfast next morning, Dudley, Uncle Vernon and Aunt Petunia are already sitting at the kitchen table. They're watching Dudley's new tv, a present from his parents. Harry hears a news report about an escaped convict, Sirius Black, who is armed and extremely dangerous.
• Aunt Marge, Uncle Vernon's sister, will come to visit today. She does not like Harry. Once, when Harry had trodden on the paw of her dog, Ripper, and it had chased Harry into a tree, she had refused to call the dog off until past midnight. Uncle Vernon warns Harry to be polite, to 'not do any funny stuff' and to stick to the story that Harry attends St. Brutus's Secure Centre for Incurably Criminal Boys.
• Harry tries to get the signed permission to visit Hogsmeade from Uncle Vernon by saying "the signed permission will make him remember better the things to say and do while Aunt Marge is there". Uncle Vernon will see if all goes right and then take a look at the form.
• Aunt Marge arrives. Harry takes her suitcase upstairs and goes back to the kitchen. Aunt Marge is telling her brother that her dogs are taken care by Colonel Fubster. She starts humiliating Harry by berating him.
• The next day Harry suffers more of Marge's dislike for him, only restraining himself by thinking of the Hogsmeade form and focussing his thoughts on his Handbook of Do-it-Yourself Broomcare. On the final evening of Marge's stay she starts saying cruel things about Harry's parents. Harry, having difficulty restraining himself, tries to force himself to remember page twelve of his book A Charm to Cure Reluctant Reversers. Aunt Marge's insults get worse and Harry snaps. He causes his Aunt Marge to start swelling like a balloon, drifting up in the air. In panic, Harry takes his trunk from the cupboard, takes his stuff from his room and flees from the house
