"Yes," said Harry stiffly.
"There's no need to call me 'sir' Professor."
The words had escaped him before he knew what he was saying.
I make mistakes like the next man. In fact, being - forgive me - rather cleverer than most men, my mistakes tend to be correspondingly huger.Failures & Mistakes, IntelligenceAlbus Dumbledore in Harry Potter and the Half-Blood Prince

"Ron!", she said furiously. "Don't you ever let me see you throwing knives again!"
"I won't," said Ron, "let you see," he added under his breath, as he turned back to the sprout mountain.
"What do you like me to call you when we’re alone together?"
"Mollywobbles," whispered a mortified Mrs Weasley into the crack at the edge of the door.
I enjoyed the meetings, too. It was like having friends.Luna Lovegood in Harry Potter and the Half-Blood Prince
It is the unknown we fear when we look upon death and darkness, nothing more.Albus Dumbledore in Harry Potter and the Half-Blood Prince
"And the steam rising in characteristic spirals," said Hermione enthusiastically, "and it's supposed to smell differently to each of us, according to what attracts us, and I can smell freshly mown grass and new parchment and -"
But she turned slightly pink and did not complete the sentence.
McGonagall: "Why is it, when something bad happens, it's always you three?"
Ron: "Believe me, professor, I've been asking myself the exact same thing for the past six years."
Yes, it is easy to see that nearly six years of magical education have not been wasted on you, Potter. Ghosts are transparent.GhostsSeverus Snape in Harry Potter and the Half-Blood Prince
I know what you are known as. But to me, you will always be Tom Riddle. It is one of the irritating things about old teachers. I am afraid that they never quite forget their charges' youthful beginnings.Albus Dumbledore in Harry Potter and the Half-Blood Prince
Yes, Harry, blessed as I am with extraordinary brainpower, I understood everything you told me. I think you might even consider the possibility that I understood more than you did.Albus Dumbledore in Harry Potter and the Half-Blood Prince
Slughorn: "Exactly how did you get out of the castle, Harry?"
Harry: "Through the front door, sir."
"How do you spell 'belligerent'?" said Ron, shaking his quill very hard while staring at his parchment. "It can't be B-U-M-"
"No, it isn't," said Hermione, pulling Ron's essay toward her. "And 'augury' doesn't begin O-R-G either. What kind of quill are you using?"
"It's one of Fred and George's Spell-Check ones, but I think the charm must be wearing off."

I have experimented; I have pushed the boundaries of magic further, perhaps, than they have ever been pushed.Voldemort / Tom Riddle in Harry Potter and the Half-Blood Prince
Ron: "Well, you can't break an Unbreakable Vow."
Harry: "I'd worked that much out for myself, funnily enough."
You know, at times, I forget how much you've grown. At times, I still se the small boy from the cupboard.Albus Dumbledore in Harry Potter and the Half-Blood Prince
"Voldemort was, I believe, more attached to this school than he has ever been to a person. Hogwarts was where he had been happiest; the first and only place he had felt at home."
Harry felt slightly uncomfortable at these words, for this was exactly how he felt about Hogwarts, too.
You seem cleverer than Fudge, so I'd have thought you'd have learned from his mistakes. He tried interfering at Hogwarts. You might have noticed he's not Minister any more, but Dumbledore's still Headmaster.Harry James Potter in Harry Potter and the Half-Blood Prince
"But for heaven's sake - you're wizards! You can do magic! Surely you can sort out - well - anything!"
Scrimgeour turned slowly on the spot and exchanged an incredulous look with Fudge, who really did manage a smile this time as he said kindly, "The trouble is, the other side can do magic too, Prime Minister."
I like a nice chat before I go to bed. Now all you do is ready that bloody book. It's just like being with Hermione.Ron Weasley in Harry Potter and the Half-Blood Prince

Hermione: "There's been a lot of talk recently that Dumbledore got a bit old."
Harry: "Rubbish! Well, he's only... what is he?"
Ron: "150? Give or take a few years."
Waitress: "Harry Potter. Who's Harry Potter?"
Harry: "Oh, no one. Bit of a tosser, really."

Scrimgeour: "Dumbledore's man through and through, aren't you, Potter?"
Harry: "Yeah, I am. Glad we straightened that out."
Just like your mother, you're unfailingly kind. A trait people never fail to undervalue, I'm afraid.Albus Dumbledore in Harry Potter and the Half-Blood Prince
You have never treated Harry as a son. He has known nothing but neglect and often cruelty at your hands. The best that can be said is that he has at least escaped the appalling damage you have inflicted upon the unfortunate boy sitting between you.Albus Dumbledore in Harry Potter and the Half-Blood Prince
Every day, every hour, this very minute, perhaps, dark forces attempt to penetrate this castle's walls. But in the end, their greatest weapon is you.HogwartsAlbus Dumbledore in Harry Potter and the Half-Blood Prince
Luna did not seem to have noticed; she appeared singularly uninterested in such mundane things as the score, and kept attempting to draw the crowd's attention to such things as interestingly shaped clouds and the possibility that Zacharias Smith, who had so far failed to maintain possession of the Quaffle for long than a minute, was suffering from sonething called "Loser's Lurgy".Luna Lovegood in Harry Potter and the Half-Blood Prince
At Hogwarts, you'll be taught not only how to use magic, but how to control it.HogwartsAlbus Dumbledore in Harry Potter and the Half-Blood Prince
"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 combination of Dark Magic and gum disease."Luna Lovegood in Harry Potter and the Half-Blood Prince
Slughorn: "You've been a very long time. Upset stomach?"
Dumbledore: "No, I was merely reading the Muggle magazines, I do love knitting patterns."
It was important, Dumbledore said, to fight, and fight again, and keep fighting, for only then could evil be kept at bay, though never quite eradicated.FightingAlbus Dumbledore in Harry Potter and the Half-Blood Prince
Ron: "There is no way they'd let me be a Death Eater! My whole family are blood traitors! That's as bad as Muggle-borns to Death Eaters!"
Harry: "And they'd love to have me. We'd be best pals if they didn't keep trying to do me in."
From this point forth, we shall be leaving the firm foundation of fact and journeying together through the murky marshes of memory into thickets of wildest guesswork.Albus Dumbledore in Harry Potter and the Half-Blood Prince
Harry looked around; there was Ginny running toward him; she had a hard blazing look in her face as she threw her arms around him. And without thinking, without planning it, without worrying about the fact that fifty people were watching, Harry kissed her. After several long moments, or it might have been half an hour-or possibly several sunlit days- they broke apart.Harry Potter and the Half-Blood Prince
For future reference, Harry, it is raspberry... although of course, if I were a Death Eater, I would have been sure to research my own jam preferences before impersonating myself.Albus Dumbledore in Harry Potter and the Half-Blood Prince
