J.K. Rowling, Harry Potter and the Sorcerer's Stone

"It was one of those rare occasions when the true story is even more strange and exciting than the wild rumours."

"You might belong in Hufflepuff, Where they are just and loyal, Those patient Hufflepuffs are true and unafriad of toil"

"Stange how nearsighted being invisible can make you - said Dumbledore"

"They stuff people’s heads down the toilet the first day at Stonewall,” he told Harry. “Want to come upstairs and practice?”“No, thanks,” said Harry. “The poor 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."

"Honestly, woman, you call yourself our mother?"

"I'm a what" gasped Harry."A wizard, o' course," said Hagrid, sitting back down on the sofa, which groaned and sank even lower, "an' a thumpin' good'un I'd say, once yeh've been trained up a bit. With a mum an' dad like yours, what else would yeh be?"

"Do you mean to tell me’, he growled a 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 were’nt bad.’I know some things,’ he said. ’ I can, you know, do maths and stuff.’But Hagrid simply waved his hand and said, ‘About our world, I mean. Your world. My world. Yer’ parents world.’ ‘What world?’Hagrid looked at though he was about to explode.‘DURSLEY!’ he boomed. Uncle Vernon, who had gone very pale, whispered something that sounded like ’Mimblewimble’. Hagrid stared wildly at Harry.‘But yeh must know about yer mum and dad’, he said. ’I mean, they’re famous. You’re famous. ‘What? My - my mum and dad weren’t famous, were they?’‘Yeh don’ know... yeh don’ know...’ Hagrid ran his fingers through his hair, fixing Harry with a bewildered stare.‘Yeh don’ know what yeh are?’ he said finally. Uncle Vernon suddenly found his voice.‘Stop!’ he commanded, ’stop right there, sir! I forbid you to tell the boy anything!’A braver man than Vernon dudley would have quailed under the furious look Hagrid now gave him; when Hagrid spoke, his every syllable trembled with rage.‘You never told him? Never told him what was in the latter Dumbledore left fer him? I was there! I saw Dumbledore leave it, Dursley! An’ you kept it from him all these years?’‘Kept what from me?’ said Harry eagerly.‘STOP! I FORBID YOU!’ yelled Uncle Vernon in panic. Aunt Petunia gave a gasp of horror.’Ah, go boil yer heads, both of yeh,’ said Hagrid. ‘Harry - yer a wizard."

"The Chasers throw the Quaffle and put it through the hoops to score,” Harry recited. “So — that’s sort of like basketball on broomsticks with six hoops, isn’t it?”“What’s basketball?” said Wood curiously.“Never mind,” said Harry quickly."

"It does not do to dwell on dreams and forget to live. Remember that. -Albus Dumbledore"

"Don't, Ginny, we'll send you loads of owls. We'll send you a Hogwarts toilet seat. George!Only joking, Mum."

"I just take the train from platform nine and three-quarters," - Harry Potter"

"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.”He held out his hand to shake Harry’s, but Harry didn’t take it. “I think I can tell who the wrong sort are for myself, thanks,” he said coolly."

"Hey, look — Harry’s got a Weasley sweater, too!”Fred and George were wearing blue sweaters, one with a large yellow F on it, the other a G.“Harry’s is better than ours, though,” said Fred, holding up Harry’s sweater. “She obviously makes more of an effort if you’re not family."

"Dudley thought for a moment. It looked like hard work."

"Friday was an important day for Harry and Ron. They finally managed to find their way down to the Great Hall without getting lost once."

"Is it true" he said. "They're saying all down the train that Harry Potter's in this compartment. So it's you, is it"Yes," said Harry. He was looking at the other boys. Both of were thickset and looked like bodyguards."Oh, this is Crabbe and this is Goyle," said the pale boy carelssly, noticing where Harry was looking. "And my name's Malfoy, Draco Malfoy." 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."

"Or yet in wise old Ravenclaw, if you've a ready mind, Where those of wit and learning, Will always find their kind."

"It's levi Osa, not levio SA!"

"There are some things you can't share without ending up liking each other."

"Swish and flick."
