The last week of term became increasingly boisterous as it progressed. Rumors about the Yule Ball were flying everywhere, though Harry didn’t believe half of them—for instance, that Dumbledore had bought eight hundred barrels of mulled mead from Madam Rosmerta. It seemed to be fact, however, that he had booked the Weird Sisters. Exactly who or what the Weird Sisters were Harry didn’t know, never having had access to a wizard’s wireless, but he deduced from the wild excitement of those who had grown up listening to the WWN (Wizarding Wireless Network) that they were a very famous musical group.

Some of the teachers, like little Professor Flitwick, gave up trying to teach them much when their minds were so clearly elsewhere; he allowed them to play games in his lesson on Wednesday, and spent most of it talking to Harry about the perfect Summoning Charm Harry had used during the first task of the Triwizard Tournament. Other teachers were not so generous. Nothing would ever deflect Professor Binns, for example, from plowing on through his notes on goblin rebellions—as Binns hadn’t let his own death stand in the way of continuing to teach, they supposed a small thing like Christmas wasn’t going to put him off. It was amazing how he could make even bloody and vicious goblin riots sound as boring as Percy’s cauldron-bottom report. Professors McGonagall and Moody kept them working until the very last second of their classes too, and Snape, of course, would no sooner let them play games in class than adopt Harry. Staring nastily around at them all, he informed them that he would be testing them on poison antidotes during the last lesson of the term.

“Evil, he is,” Ron said bitterly that night in the Gryffindor common room. “Springing a test on us on the last day. Ruining the last bit of term with a whole load of studying.”

“Mmm . . . you’re not exactly straining yourself, though, are you?” said Hermione, looking at him over the top of her Potions notes. Ron was busy building a card castle out of his Exploding Snap pack—a much more interesting pastime than with Muggle cards, because of the chance that the whole thing would blow up at any second.

“It’s Christmas, Hermione,” said Harry lazily; he was rereading Flying with the Cannons for the tenth time in an armchair near the fire.

Hermione looked severely over at him too. “I’d have thought you’d be doing something constructive, Harry, even if you don’t want to learn your antidotes!”

“Like what?” Harry said as he watched Joey Jenkins of the Cannons belt a Bludger toward a Ballycastle Bats Chaser.

“That egg!” Hermione hissed.

“Come on, Hermione, I’ve got till February the twenty-fourth,” Harry said.
