“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.”
“Youth can not know how age thinks and feels. But old men are guilty if they forget what it was to be young.”
“This is precisely why I loathed being a teacher! Young people are so infernally convinced that they are absolutely right about everything. Has it not occurred to you, my poor puffed-up poppinjay, that there might be an excellent reason why the Headmaster of Hogwarts is not confiding every tiny detail of his plans to you? Have you never paused, while feeling hard-done-by, to note that following Dumbledore's orders has never yet led you into harm? No. No, like all young people, you are quite sure that you alone feel and think, you alone recognise danger, you alone are the only one clever enough to realise what the Dark Lord may be planning.”
“Professor Dumbledore. Can I ask you something?" "Obviously, you've just done so," Dumbledore smiled. "You may ask me one more thing, however." "What do you see when you look in the mirror?" "I? I see myself holding a pair of thick, woolen socks." Harry stared."One can never have enough socks," said Dumbledore. "Another Christmas has come and gone and I didn't get a single pair. People will insist on giving me books."It was only when he was back in bed that it struck Harry that Dumbledore might not have been quite truthful. But then, he thought, as he shoved Scabbers off his pillow, it had been quite a personal question.”
“I think so,' said Professor McGonagall dryly, 'we teachers are rather good at magic, you know.”
“Ah" said Dumbledore gently, "Yes I thought we might hit that little snag!""Snag?" said Fudge, his voice still vibrating with joy. "I see no snag, Dumbledore!""Well," said Dumbledore apologetically, "I'm afraid I do.""Oh, really?""Well it's just that you seem to be labouring under the delusion that I am going to -- come quietly. I am afraid I am not going to come quietly at all, Cornelius. I have absolutely no intention of being sent to Azkaban. I could break out, of course -- but what a waste of time, and frankly, I can think of a whole host of things I would rather be doing.”
“Don’t put your wand there, boy!” roared Moody. “What if it ignited? Better wizards than you have lost buttocks, you know!” “Who d’you know who’s lost a buttock?” the violet-haired woman asked Mad-Eye interestedly. “Never you mind, you just keep your wand out of your back pocket!” growled Mad-Eye. “Elementary wand safety, nobody bothers about it anymore . . .” He stumped off toward the kitchen. “And I saw that,” he added irritably, as the woman rolled her eyes at the ceiling.”
