J.K. Rowling, Harry Potter and the Half-Blood Prince

"It was, he thought, the difference between being dragged into the arena to face a battle to the death and walking into the arena with your head held high. Some people, perhaps, would say that there was little to choose between the two ways, but Dumbledore knew - and so do I, thought Harry, with a rush of fierce pride, and so did my parents - that there was all the difference in the world."

"What do I care how 'e looks? I am good-looking enough for both of us, I theenk! All these scars show is zat my husband is brave!"

"The thing about growing up with Fred and George,"said Ginny thoughtfully, "is that you sort of start thinking anything's possible if you've got enough nerve."

"I was supposed to be waiting up here when you got back, only your Phoenix lot got in the way...”“Yes, they do that,” said Dumbledore."

"Am I about to discover where you, Ron, and Hermione disappeared to while you were supposed to be in the back room of Fred and George's shop?''How did you...?''Harry, please. You're talking to the man who raised Fred and George."

"When you have seen as much of life as I have, you will not underestimate the power of obsessive love."

"I am not worried, Harry,"said Dumbledore, his voice a little stronger despite the freezing water. "I am with you."

"I don't mean to be rude—"he began, in a tone that threatened rudeness in every syllable."Yet, sadly, accidental rudeness occurs alarmingly often,"Dumbledore finished the sentence gravely."

"Killing is not so easy as the innocent believe."

"Why are you worrying about YOU-KNOW-WHO, when you should be worrying about YOU-NO-POO? The constipation sensation that's gripping the nation!"

"It's going to be all right, sir,"Harry said over and over again, more worried by Dumbledore's silence than he had been by his weakened voice. "We're nearly there ... I can Apparate us both back ... don't worry ...""I am not worried, Harry,"said Dumbledore, his voice a little stronger despite the freezing water. "I am with you."

"I am not worried, Harry,"said Dumbledore, his voice a little stronger despite the freezing water. "I am with you."

"I am a wizard, not a baboon brandishing a stick."

"Nobody's ever asked me to a party before, as a friend. Is that why you dyed your eyebrow, for the party? Should I do mine too?"

"It is the unknown we fear when we look upon death and darkness, nothing more."

"I don't think you should be an Auror, Harry,"said Luna unexpectedly. Everybody looked at her. "The Aurors are part of the Rotfang Conspiracy, I thought everyone knew that. They're working to bring down the Ministry of Magic from within using a mixture of dark magic and gum disease."

"An Unbreakable Vow?"said Ron, looking stunned. "Nah, he can’t have.... Are you sure?""Yes I’m sure,"said Harry. "Why, what does it mean?""Well, you can’t break an Unbreakable Vow...""I’d worked that much out for myself, funnily enough."

"It is impossible to manufacture or imitate love."

"Snape raised his wand and pointed it directly at Dumbledore."Avada Kedavra!"

"Sometimes you remind me a lot of James. He called it my 'furry little problem' in company. Many people were under the impression that I owned a badly behaved rabbit."
