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

"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."

"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."

"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."

"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!"

"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 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."

"I see a light in the kitchen. Let us not deprive Molly any longer of the chance to deplore how thin you are."

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

"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."

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

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

"It is impossible to manufacture or imitate love."

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

"Well you seemed too busy to call him a prat and I thought someone should."

"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."

"Let us step into the night and pursue that flighty temptress, adventure."

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

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

"Dumbledore says people find it far easier to forgive others for being wrong than being right."
