"Now, you two – this year, you behave yourselves. If I get one more owl telling me you've – you've blown up a toilet or –""Blown up a toilet? We've never blown up a toilet.""Great idea though, thanks, Mum."

"No, thanks,"said Harry. "The toilet's never had anything as horrible as your head down it— it might be sick."Then he ran, before Dudley could work out what he'd said."

"There is no good and evil, there is only power and those too weak to seek it."

"Your mother died to save you. If there is one thing Voldemort cannot understand, it is love. Love as powerful as your mother's for you leaves it's own mark. To have been loved so deeply, even though the person who loved us is gone, will give us some protection forever."

"It does not do to dwell on dreams and forget to live."

"Nitwit! Blubber! Oddment! Tweak!"

"Your mother died to save you. If there is one thing Voldemort cannot understand, it is love. Love as powerful as your mother's for you leaves it's own mark. To have been loved so deeply, even though the person who loved us is gone, will give us some protection forever."

"There is no good and evil, there is only power and those too weak to seek it."

"Ah, music,"he said, wiping his eyes. "A magic beyond all we do here!"

"It takes a great deal of bravery to stand up to our enemies, but just as much to stand up to our friends."

"As much money and life as you could want! The two things most human beings would choose above all - the trouble is, humans do have a knack of choosing precisely those things that are worst for them."

"So light a fire!"Harry choked. "Yes...of course...but there's no wood!"... "HAVE YOU GONE MAD!"Ron bellowed. "ARE YOU A WITCH OR NOT!"

"The truth."Dumbledore sighed. "It is a beautiful and terrible thing, and should therefore be treated with great caution."

"Alas! Earwax!"

"Do you mean ter tell me,"he growled at the Dursleys, "that this boy—this boy!—knows nothin' abou'—about ANYTHING?"Harry thought this was going a bit far. He had been to school, after all, and his marks weren't bad."I know some things,"he said. "I can, you know, do math and stuff."

"He didn't realize that love as powerful as your mother's for you leaves its own mark."

"Everybody finished the song at different times. At last, only the Weasley twins were left singing along to a very slow funeral march."

"I hope you're pleased with yourselves. We could all have been killed - or worse, expelled. Now if you don't mind, I'm going to bed."

"There are some things you can't share without ending up liking each other, and knocking out a twelve-foot mountain troll is one of them."

"They heard the click of the mail slot and flop of letters on the doormat. "Get the mail, Dudley,"said Uncle Vernon from behind his paper. "Make Harry get it.""Get the mail, Harry.""Make Dudley get it.""Poke him with your Smelting stick, Dudley."
