“Do you—do you think I want to—do you think I give a—I DON'T CARE WHAT YOU HAVE TO SAY!" Harry roared."You will," said Dumbledore sadly. "Because you are not nearly as mad at me as you ought to be. If you are to attack me, as I know you are close to doing, I would like to have thoroughly earned it.”
“I think they ought to know. You do them a disservice by not confiding something this important to them.”“I didn’t want —”“— to worry or frighten them?” said Dumbledore, surveying Harry over the top of his half-moon spectacles. “Or perhaps, to confess that you yourself are worried and frightened? You need your friends, Harry. As you so rightly said, Sirius would not have wanted you to shut yourself away.”
“Let me out," Harry said again."No," Dumbledore repeated."If you don't - if you keep me in here - if you don't let me-""By all means continue destroying my possessions," said Dumbledore. "I daresay I have too many.”
“Do you know what I think, Potter?' said Snape, very quietly. "I think that you are a liar and a cheat and that you deserve detention with me every Saturday until the end of term. What do you think, Potter?”
“Of course we still want to know you!" Harry said, staring at Hagrid."You don't think anything that Skeeter cow - sorry, Professor," he added quickly, looking at Dumbledore."I have gone temporarily deaf and haven't any idea what you said, Harry," said Dumbledore, twiddling his thumbs and staring at the ceiling.”
“I DON'T CARE!" Harry yelled at them, snatching up a lunascope and throwing it into the fireplace. "I'VE HAD ENOUGH, I'VE SEEN ENOUGH, I WANT OUT, I WANT IT TO END, I DON'T CARE ANYMORE!""You do care," said Dumbledore. He had not flinched or made a single move to stop Harry demolishing his office. His expression was calm, almost detached. "You care so much you feel as though you will bleed to death with the pain of it.”
“No, it was honest," said Harry. "One of the only honest things you've said to me. You don't care whether I live or die, but you do care that I help you convince everyone you're winning the war against Voldemort.”
