"I was wondering whether you could tell me anything of Tom Riddle's [Lord Voldemort's] history? I think he was born here in the orphanage . . . he stayed in the orphanage and he's been here ever since. . . He was a funny baby too. He hardly ever cried, you know. And then, when he got a little older, he was . . . odd . . . He scares the other children."

from Harry Potter and the Half-Blood Prince by J.K. Rowling
