In the back of the shop, a boy with a pale, pointed face was standing on a footstool while a second witch pinned up his long black robes. Madam Malkin stood Harry on a stool next to him, slipped a long robe over his head, and began to pin it to the right length.

"Hello," said the boy, "Hogwarts, too?"

-

He held out his hand to shake Harry's, but Harry didn't take it.

-Harry Potter and the Sorcerer's Stone


The sound of running feet pounding down the stone corridor echoed off the walls.

"Draco!"

Draco paused at the shout from behind him. Fixing a sneer on his face, he pivoted around and waited.

"Yes, Potter?"

Hesitating for a moment, Harry stuck out his hand. Draco briefly glanced down, and then raised his head again to stare at Harry, eyebrows furrowed. Harry's small smile wavered, then, taking a deep breath, he spoke.

"Hello. Hogwarts too?"

Confused, Draco tilted his head slightly, and as he realized what was meant by those three words, he reached out and grasped Harry's hand.
