Quotes from Harry Potter and the Half-Blood Prince

"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.

I make mistakes like the next man. In fact, being - forgive me - rather cleverer than most men, my mistakes tend to be correspondingly huger.

People find it far easier to forgive others for being wrong than being right.

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

Have you any idea how much tyrants fear the people they oppress? All of them realize that, one day, amongst their many victims, there is sure to be one who rises against them and strikes back!

...yet, sadly, accidental rudeness occurs alarmingly often. Best to say nothing at all, my dear man.

"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.

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

"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.

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.

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.

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."

Only time I've ever seen Dad as angry as Mum. Fred reckons his left buttock has never been the same since.

Oh, to be young, and to feel love's keen sting.

Slughorn: "Dear fellow, however did you manage to kill it?"
Hagrid: "Kill it? Me oldest friend, he was."

There can be no light without the dark. And so it is with magic. Myself, I always strive to live within the light.

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.

"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.

"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.

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."

Greatness inspires envy, envy engenders spite, spite spawns lies.

Harry: "And Ginny, don't call Ron a prat, you're not the Captain of this team."
Ginny: "Well, you seemed too busy to call him a prat and I thought someone should."

I don't remember you rushing to my defence when I was trying to tell everyone Voldemort was back. The Ministry wasn't so keen to be pals last year.

The time is long gone when I could frighten you with a burning wardrobe and force you to make repayment for your crimes. But I wish I could, Tom.

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.

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.

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.

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".

At Hogwarts, you'll be taught not only how to use magic, but how to control it.

"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."

Phineas Nigellus: "I can't see why the boy should be able to do it better than you, Dumbledore."
Albus Dumbledore: "I wouldn't expect you to, Phineas."

Flitwick: "There you are! We've been looking everywhere for you two. Now, names?"
Harry: "Professor Flitwick, you've known me for five years."
Flitwick: "No exceptions, Potter!"

Now, now, boys. A little less talk, a little more action... Let me see you try.

Hogwarts should be Dumbledore's final resting place.

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.

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."
