“Detention, Saturday night, my office,” said Snape. “I do not take cheek from anyone, Potter . . . not even ‘the Chosen One.’”

“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.”

“Anyway, members of the Inquisitorial Squad do have the power to dock points so, Granger, I'll have five from you for being rude about our new Headmistress. Macmillan, five for contradicting me. Five because I don't like you, Potter. Weasley, your shirt's untucked, so I'll have another five for that. Oh yeah, I forgot, you're a Mudblood, Granger, so ten off for that.”

Ron gave a slight cough, which might have been hiding a snigger. Draco Malfoy looked at him. "Think my name's funny, do you? No need to ask who you are. My father told me all the Weasleys have red hair, freckles, and more children than they can afford."He turned back to Harry. "You'll soon find out some wizarding families are much better than others, Potter. You don't want to go making friends with the wrong sort. I can help you there.”
