Severus couldn't imagine why the world wouldn't be a much better place without Quidditch, but knew there was no reason to delve into that - he was quite alone in his opinions, he knew, and he was more than happy to leave Quidditch entirely to someone else.
He glanced at the proffered hand, inclined to ignore it entirely. Neither of them were here to be friendly; it hardly mattered to him whether anyone found him pleasant or not. But he stood after a moment, and took his hand briefly - only so as not to start yet another Gryffindor Head off on the wrong foot, he told himself, because Merlin knew it would only get harder and harder to find willing candidates. "It doesn't matter to me," he said, flat. Ten minutes ago he would have pounced on Sir, and he had no idea why he shouldn't - perhaps he was only being contrary. "I'm sure you'll find something to your liking. Good day."
