Harry Potter and the Chamber of Secrets
"I hope my son will amount to more than a thief or a plunderer, Borgin," said Mr. Malfoy coldly, and Mr. Borgin said quickly, "No offense, sir, no offense meant —"
"Though if his grades don't pick up," said Mr. Malfoy, more coldly still, "that may indeed be all he is fit for —"
"It's not my fault," retorted Draco. "The teachers all have favorites, that Hermione Granger "
"I would have thought you'd be ashamed that a girl of no wizard family beat you in every exam," snapped Mr. Malfoy. (4.83-86)
Mrs. Weasley's yells, a hundred times louder than usual, made the plates and spoons rattle on the table, and echoed deafeningly off the stone walls.

"— LETTER FROM DUMBLEDORE LAST NIGHT, I THOUGHT YOUR FATHER WOULD DIE OF SHAME, WE DIDN'T BRING YOU UP TO BEHAVE LIKE THIS, YOU AND HARRY COULD BOTH HAVE DIED —" (6.18-19)
"I don't really understand Quidditch," said Colin breathlessly. "Is it true there are four balls? And two of them fly around trying to knock people off their brooms?"
"Yes," said Harry heavily, resigned to explaining the complicated rules of Quidditch. "They're called Bludgers. There are two Beaters on each team who carry clubs to beat the Bludgers away from their side. Fred and George Weasley are the Gryffindor Beaters." (7.22-23)
