“I’m a teacher! A teacher, Potter! How dare yeh threaten ter break down my door!”“I’m sorry, sir,” said Harry, emphasizing the last word.Hagrid looked stunned. “Since when have yeh called me ‘sir’?” “Since when have you called me ‘Potter’?”

“Do you remember me telling you we are practicing non-verbal spells, Potter?""Yes," said Harry stiffly."Yes, sir.""There's no need to call me "sir" Professor."The words had escaped him before he knew what he was saying.”

“Malfoy glanced around. Harry knew he was checking for signs of teachers. Then he looked back at Harry and said in a low voice, "You're dead, Potter."Harry raised his eyebrows. "Funny," he said, "you'd think I'd have stopped walking around...”

“Killed?" said Hagrid loudly, staring down at Harry. "Snape killed? What're yeh on abou', Harry?""Dumbledore," said Harry. "Snape killed... Dumbledore.”

“She should've interviewed Snape," said Harry grimly. "He'd give her the goods on me any day. "Potter has been crossing lines ever since he first arrived at this school...”

“But Dobby shouted, "You shall not harm Harry Potter! ... He got up, face livid, and pulled out his wand, but Dobby raised a long, threatening finger. "You shall go now," he said fiercely, pointing down at Mr. Malfoy. "You shall not touch Harry Potter. You shall go now.”

“Ah, go boil yer heads, both of yeh", said Hagrid. “Harry — yer a wizard.”
