Harry Potter and his mean cousin Dudley are outside at around 7 o'clock. All of a sudden everything gets a whole lot darker as a dementor comes. Harry tries to stop it with a spell.
Because he used magic in front of a muggle (a non-wizard) he gets in trouble from the Ministry of Magic (like the wizard government), and his Uncle and Aunt. On top of that, his friends have not talked to him since school ended last year.
You are in trouble for using a spell in front of a muggle.
I got in trouble from the Ministry of Magic, from my Uncle and Aunt, and my friends aren't contacting me with their owls!
Harry is locked in his room and his Uncle, Aunt and cousin Dudley are out because, apparently, they won the best lawn award. While they were gone Harry hears noise downstairs. Wizards and a witch from the Order of the Pheonix had come to the house to get Harry.
My Uncle, Aunt and cousin Dudley aren't home and there is noise downstairs.
Harry packs his bags and heads off with the wizards and witch.
Come with us to our headquarters.
They fly on their brooms to Number Twelve, Grimmauld Place.
