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

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

"When we come face-to-face with one down a dark alley, we're going to be having a shufti to see if it's solid, aren't we, we're not going to be asking, 'Excuse me, are you the imprint of a departed soul?"

"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?"

"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."

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

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

"You could say sorry,"suggested Harry bluntly. "What, and get attacked by another flock of canaries?"muttered Ron."What did you have to imitate her for?""She laughed at my mustache!""So did I, it was the stupidest thing I've ever seen."

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

"Yes, alive,” said Fudge. “That is — I don’t know — is a man alive if he can’t be killed? I don’t really understand it, and Dumbledore won’t explain properly — but anyway, he’s certainly got a body and is walking and talking and killing, so I suppose, for the purposes of our discussion, yes, he’s alive."

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

"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!"

"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."

"You are protected, in short, by your ability to love!"

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

"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."

"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."

"Dumbledore will only leave from Hogwarts when there are none loyal to him!"

"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."

"It is impossible to manufacture or imitate love."

"Oh, there you are, Albus,' he said. 'You've been a very long time. Upset stomach?''No, I was merely reading the Muggle magazines,' said Dumbledore. 'I do love knitting patterns."
