"Nobody's ever asked me to a party before, as a friend. Is that why you dyed your eyebrow, for the party? Should I do mine too?"

"Dumbledore says people find it far easier to forgive others for being wrong than being right."

"Killing is not so easy as the innocent believe."

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