" They’re not waiters, they’re house-elves. I read about them yesterday,” Ralph said, happily munching half a sausage. The other half was speared on the end of his fork, which he used like a pointer, indicating the elves. “They work downstairs. They’re like the elves in that kids’ story. The ones that came at night and did all the work for the cobbler. "
