"How can you go to the moon?"

"Muggles have flying machines, like trains, that can carry people through the sky."

"Yeah and the best ones can breach the atmosphere and go to the Moooooon!"

"I'm sure wizards could go to the moon, but we have more important things to worry about." 

"Like?"

"Well, what about arithmancy? Muggles can't be more advanced than us there." 

"Erm. I haven't really looked it up but what I did look at seemed like pretty basic maths?"

"Arthmancy is advanced stuff. Obviously you didn't understand what you were reading." 

"I understood all the things I read, though. I know calculus," he says proudly. "It's way more difficult than that."

"You know calculus?"

He grunts and goes back to his seat.

"Yeah! I studied it by myself, it sounded fun, and it's way easier than most people say."

"Are you going to do that with the subjects here, too?"

"Yeah. Class is useless."

"Louder, I think the Headmistress didn't hear you." 

He giggles. "I learn better alone."

"Why did you come here then?" 

"The books are here and I can't practise magic back home. Also the people."

"Those are good reasons. How do you learn on your own if you aren't smart, though? I'm not smart." 

"I don't think it's about being smart, I think it's just about, like, different ways of learning and doing things? Like, some people are good at learning when other people teach them, some people aren't."

"I guess I'll find out. Do you want to talk to house elves with me?"

"What are those?"

"The...species...that make the food. They like to serve."

Slow blink. "What?"

"Yeah. I haven't met one before, so we'll see."
