“Harry, just go down to the lake tomorrow, right, stick your head in, yell at the merpeople to give back whatever they’ve nicked, and see if they chuck it out. Best you can do, mate.”

“Can you think what the Mirror of Erised shows us all?" Harry shook his head."Let me explain. The happiest man on earth would be able to use the Mirror of Erised like a normal mirror, that is, he would look into it and see himself exactly as he is. Does that help." Harry thought. Then he said slowly, "It shows us what we want... whatever we want..." "Yes and no," said Dumbledore quietly. "It shows us nothing more or less than the deepest, most desperate desire of our hearts. You, who have never known your family, see them standing around you. Ronald Weasley, who has always been overshadowed by his brothers, sees himself standing alone, the best of all of them. However, this mirror will give us neither knowledge or truth. Men have wasted away before it, entranced by what they have seen, or been driven mad, not knowing if what it shows is real or even possible."The Mirror will be moved to a new home tomorrow, Harry, and I ask you not to go looking for it again. If you ever do run across it, you will now be prepared. It does not do to dwell on dreams and forget to live, remember that. Now, why don't you put that admirable cloak back on and get off to bed.”

“Harry looked down and saw deep green mountains and lakes, coppery in the sunset.”

“Yeah, Quirrell was a great teacher. There was just that minor drawback of him having Lord Voldemort sticking out of the back of his head!”

“A fierce battle was raging inside Harry's brain:She's Ron's sister.But she's ditched Dean!She's still Ron's sister.I'm his best mate!That'll make it worse.If I talked to him first-He'd hit you.What if I don't care?He's your best mate!”

“They stuff people’s heads down the toilet the first day at Stonewall,” he told Harry. “Want to come upstairs and practice?”“No, thanks,” said Harry. “The poor toilet’s never had anything as horrible as your head down it — it might be sick.” Then he ran, before Dudley could work out what he’d said.”

“Dudley had been accepted at Uncle Vernon's old private school, Smeltings...Harry, on the other hand, was going to Stonewall High, the local public high school. Dudley thought this was very funny. "They stuff people's heads down the toilet the first day at Stonewall," he told Harry. "Want to come upstairs and practice?" "No, thanks," said Harry. "The poor toilet's never had anything as horrible as your head down it - it might be sick." Then he ran, before Dudley could work out what he'd said.”
