"Mr. Moony presents his compliments to Professor Snape, and begs him to keep his abnormally large nose out of other people's business.Mr. Prongs agrees with Mr. Moony, and would like to add that Professor Snape is an ugly git.Mr. Padfoot would like to register his astonishment that an idiot like that ever became a professor.Mr. Wormtail bids Professor Snape good day, and advises him to wash his hair, the slimeball."

"He can run faster than Severus Snape confronted with shampoo."

"Do you remember me telling you we are practicing non-verbal spells, Potter?""Yes," said Harry stiffly."Yes, sir.""There's no need to call me "sir" Professor."The words had escaped him before he knew what he was saying."

"Nothing like a nighttime stroll to give you ideas."

"Harry, despite your privileged insight into Voldemort’s world (which, incidentally, is a gift any Death Eater would kill to have), you have never been seduced by the Dark Arts, never, even for a second, shown the slightest desire to become one of Voldemort’s followers!”“Of course I haven’t!” said Harry indignantly. “He killed my mum and dad!”“You are protected, in short, by your ability to love!” said Dumbledore loudly."

"Be ruthless about protecting writing days, i.e., do not cave in to endless requests to have "essential" and "long overdue" meetings on those days. The funny thing is that, although writing has been my actual job for several years now, I still seem to have to fight for time in which to do it. Some people do not seem to grasp that I still have to sit down in peace and write the books, apparently believing that they pop up like mushrooms without my connivance. I must therefore guard the time allotted to writing as a Hungarian Horntail guards its firstborn egg."

"Hope springs forever."

"Don't count your owls before they are delivered."

"Have to? Of course you have to! But only because of you, Harry, won't rest until Voldemort is finished! Think now, for once, if you have never heard of the prophecy! What would you do?"

"That's chess!" snapped Ron. "You've got to make some sacrifices!"

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

"Where your treasure is, there will your heart be also"

"Rock bottom became the solid foundation on which I rebuilt my life."

"The mistake ninety-nine percent of humanity made, as far as Fats could see, was being ashamed of what they were; lying about it, trying to be somebody else."

"I am what I am, an’ I’m not ashamed. 'Never be ashamed,’ my ol’ dad used ter say, ‘there’s some who’ll hold it against you, but they’re not worth botherin’ with."

"What's most important in a friendship? Tolerance and loyalty."

"Call him Voldemort, Harry. Always use the proper name for things. Fear of a name increases fear of the thing itself."

"You must accept the reality of other people. You think that reality is up for negotiation, that we think it's whatever you say it is. You must accept that we are as real as you are; you must accept that you are not God."

"We can't choose our fate, but we can choose others. Be careful in knowing that."

"Besides, the world isn't split into good people and Death Eaters. We've all got both light and dark inside us. What matters is the part we choose to act on. That's who we really are."

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

"There are some things you can't share without ending up liking each other, and knocking out a twelve-foot mountain troll is one of them."
