“Although people rarely died playing Quidditch, referees had been known to vanish and turn up months later in the Sahara Desert.” - Quidditch Through the Ages

“But Hogwarts is hidden,” said Hermione, in surprise. “Everyone knows that … well, everyone who’s read Hogwarts, A History, anyway.” “Just you, then,” said Ron.” - Harry Potter and the Goblet of Fire

“Don't let Ron see what's on those Slytherin's badges," she whispered urgently.
Harry looked questioningly at her, but she shook her head warningly Ron had just ambled over to them, looking lost and desparate.
"Good luck, Ron," said Hermione, standing on tiptoe and kissing him on the cheek. "And you, Harry --"
Ron seemed to come to himself slightly as they walked back across the Great Hall. He touched the spot on his face where Hermione had kissed him, looking puzzled, as though he was not quite sure what had just happened.” - Harry Potter and the Order of the Phoenix

“He had grown used to the idea that Dumbledore could solve anything.” - Harry Potter and the Prisoner of Azkaban

“Yes, well, principles are sometimes the problem, if you ask me,' said Miles. 'Often what's needed is a bit of common sense.'
'Which is the name people usually give to their prejudices,' rejoined Kay.” - The Casual Vacancy

“A tiny little wooden man [was] slowly ascending the steps to a real set of gallows, both perched on a box that read: Reusable Hangman — Spell It Or He’ll Swing!” - Harry Potter and the Half-Blood Prince

“The fates have informed me that your examination in June will concern the Orb, and I am anxious to give you sufficient practice.
Hermione snorted.
"Well honestly... 'the fates have informed her'... Who sets the exam? She does!” - Harry Potter and the Prisoner of Azkaban

“EXPECTO PATRONUM!!!” - Harry Potter and the Deathly Hallows

“The difficult thing, the glorious thing, was to be who you really were, even if that person was cruel or dangerous, particularly if cruel and dangerous. There was courage in not disguising the animal you happened to be.” - The Casual Vacancy

“Directly above them, framed in the doorway from the Brain Room, stood Albus Dumbledore, his wand aloft, his face white and furious. Harry felt a kind of electric charge surge through every particle of his body - they were saved.” - Harry Potter and the Order of the Phoenix

“I've decided to call him Norbert,' said Hagrid, looking at the dragon with misty eyes. 'He really knows me now, watch. Norbert! Norbert! Where's Mummy?'
'He's lost his marbles,' Ron muttered in Harry's ear.
'Hagrid,' said Harry loudly, 'give it a fortnight and Norbert's going to be as big as your house. Malfoy could go to Dumbledore at any moment.
Hagrid bit his lip.
'I- I know I can't jus' dump him, I can't.'
Harry suddenly turned to Ron.
'Charlie,' he said.
'You're losing it too,' said Ron. 'I'm Ron, remember?” - Harry Potter and the Sorcerer's Stone

“What must strike any intelligent witch or wizard on studying the so-called history of the Elder Wand is that every man who claims to have owned it has insisted that it is "unbeatable," when the known facts of its passage through many owners' hands demonstrate that has it not only been beaten hundreds of times, but that it also attracts trouble as Grumble the Grubby Goat attracted flies.” - The Tales of Beedle the Bard

“Help only comes to those who ask for it.”

“There was a clatter as the basilisk fangs cascaded out of Hermione's arms. Running at Ron, she flung them around his neck and kissed him full on the mouth. Ron threw away the fangs and broomstick he was holding and responded with such enthusiasm that he lifted Hermione off her feet.
"Is this the moment?" Harry asked weakly, and when nothing happened except that Ron and Hermione gripped each other still more firmly and swayed on the spot, he raised his voice. "OI! There's a war going on here!"
Ron and Hermione broke apart, their arms still around each other.
"I know, mate," said Ron, who looked as though he had recently been hit on the back of the head with a Bludger, "so it's now or never, isn't it?"
"Never mind that, what about the Horcrux?" Harry shouted. "D'you think you could just --- just hold it in, until we've got the diadem?"
"Yeah --- right --- sorry ---" said Ron, and he and Hermione set about gathering up fangs, both pink in the face.” - Harry Potter and the Deathly Hallows

“A breeze ruffled the neat hedges of Privet Drive, which lay silent and tidy under the inky sky, the very last place you would expect astonishing things to happen. Harry Potter rolled over inside his blankets without waking up. One small hand closed on the letter beside him and he slept on, not knowing he was special, not knowing he was famous, not knowing he would be woken in a few hours' time by Mrs. Dursley's scream as she opened the front door to put out the milk bottles, nor that he would spend the next few weeks being prodded and pinched by his cousin Dudley...He couldn't know that at this very moment, people meeting in secret all over the country were holding up their glasses and saying in hushed voices: "To Harry Potter - the boy who lived!” - Harry Potter and the Sorcerer's Stone

“And anyway, it’s not as though I’ll never see Mum again, is it?” - Harry Potter and the Order of the Phoenix

“You’re not by any chance writing out a new order form, are you?” said Mrs. Weasley shrewdly. “You wouldn’t be thinking of restarting Weasleys’ Wizard Wheezes, by any chance?” “Now, Mum,” said Fred, looking up at her, a pained look on his face. “If the Hogwarts Express crashed tomorrow, and George and I died, how would you feel to know that the last thing we ever heard from you was an unfounded accusation?” - Harry Potter and the Goblet of Fire

“We shall trespass upon your aunt and uncle's hospitality only a little longer.'
You will, will you?'
Yes,' said Dumbledore simply, 'I shall.” - Harry Potter and the Half-Blood Prince

“Of all the trees we could've hit, we had to get one that hits back.” - Harry Potter and the Chamber of Secrets

“I love magic!” - Harry Potter and the Goblet of Fire
