“Choice was dangerous: you had to forgo all other possibilities when you chose.”

“He chose the boy he thought most likely to be a danger to him," said Dumbledore. And notice this, Harry. He chose, not the pureblood (which, according to his creed, is the only kind of wizard worth being or knowing), but the half-blood, like himself. He saw himself in you before he had ever seen you, and in marking you with that scar, he did not kill you, as he intended, but gave you powers, and a future, which have fitted you to escape him not once, but four times so far — something that neither your parents, nor Neville’s parents, ever achieved.”

“The difficult thing, the glorious thing, was to be who you really were, even if that person was cruel or dangerous, particularly if cruel and dangerous. There was courage in not distinguishing the animal you happened to be. On the other hand, you had to avoid pretending to be more of an animal than you were: take that path, start exaggerating or faking and you became just another Cubby, just as much of a liar, a hypocrite”

“Did you know— then?” asked Harry.“Did I know that I had just met the most dangerous Dark wizard of all time? No.”

“I bet you’re not dangerous at all, are you? Are you, you great ugly brute?”

“You may, perhaps, have wondered why I never chose you as a prefect? I must cofess...that I rather thought...you had enough reponsibility to be going on with." Harry looked up at him and saw a tear trickling down Dumbledore's face into his long silver beard.”

“But if it matters to you, you'll be able to choose Gryffindor over Slytherin. The Sorting Hat takes your choice into account.""Really?""It did for me," said Harry.He had never told any of his children that before, and he saw the wonder in Albus's face when he said it.”
