“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.”
“Ah, music," he said, wiping his eyes. "A magic beyond all we do here!”
“Can't stay long, Mother," he said. "I'm up front, the prefects have got two compartments to themselves-"
"Oh, are you a prefect, Percy?" said one of the twins, with an air of great surprise. "You should have said something, we had no idea."

“Hogwarts, Hogwarts, Hoggy Warty Hogwarts,
Teach us something please,
Whether we be old and bald,
Or young with scabby knees,
Our heads could do with filling
With some interesting stuff,
For now they're bare and full of air,
Dead flies and bits of fluff,
So teach us something worth knowing,
Bring us back what we've forgot,
Just do your best, we'll do the rest,
And learn until our brains all rot...”
