Harry stood up.
“Sir — Professor Dumbledore? Can I ask you something?”
“Obviously, you’ve just done so,” Dumbledore smiled. “You may ask me one more thing, however.”
“What do you see when you look in the mirror?”
“I? I see myself holding a pair of thick, woolen socks.”
Harry stared.
“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.”
