“Anyone can speak Troll. All you have to do is point and grunt.”

“Miss Granger, you foolish girl, how could you think of tackling a mountain troll on your own? Five points will be taken from Gryffindor for this,” said Professor McGonagall. “I’m very disappointed in you.”Hermione left. Professor McGonagall turned to Harry and Ron.“Well, I still say you were lucky, but not many first years could have taken on a full-grown mountain troll. You each win Gryffindor five points.”

“You mustn’t blame yourself for the way the boy’s turned out, Vernon. If there’s something rotten on the inside, there’s nothing anyone can do about it.”

“If anyone wanted ter find out some stuff, all they’d have ter do would be ter follow the spiders. That’d lead ‘em right! That’s all I’m sayin’.”

“Writing for me is a kind of compulsion, so I don't think anyone could have made me do it, or prevented me from doing it.”

“That is the second time you have spoken out of turn, Miss Granger,” said Snape coolly. “Five more points from Gryffindor for being an insufferable know-it-all.”

“Fifty?” Harry gasped.“Fifty points each,” said Professor McGonagall, breathing heavily.“Professor — please —”“You can’t —”“Don’t tell me what I can and can’t do, Potter. I’ve never been more ashamed of Gryffindor students.”
