Matt Coulter is starting at Hogwarts this year. He is currently sitting alone in a compartment on the Hogwarts Express.
"Can I sit here?"
“Uh… yeah, sure, if you want to.”
She sits. "I'm Miranda, what's your name?"
"It's nice to meet you. What House are you hoping for?"
“What do you mean?”
"Oh, are you - okay, in regular schools there's often houses, right, to subdivide the students? But I think in Muggle schools they don't mean anything; in Hogwarts they mean things. There's four. Ravenclaw, Hufflepuff, Gryffindor, and Slytherin. If you're Muggle-born you'd probably want to stay out of Slytherin - or not tell anybody if you wind up there anyway."
“Oh. I’ve never been in a school that’s had houses. What things do they mean?”
"Er... I've been out of the country for a couple of years and I have strong opinions anyway, so some of the things I say might just be stereotypes, right? But the quick version is that Ravenclaw is for intelligence and Hufflepuff for hard work and loyalty and Gryffindor for bravery and Slytherin for ambition but there's also a lot of blood prejudice and such mixed in with Slytherin in the last several decades so you don't want to go there if you're Muggleborn. I want Ravenclaw, like my mum."
“Hmm… I like to think I’m intelligent, so I guess I’d want Ravenclaw, though Hufflepuff sounds okay too.”
"You don't get to pick your own house. A magic hat does it, Mum said, but if you're not really obviously one thing it will sort of talk to you for a bit and let you help it pick. It gets final say though."
“I see. Well, then, I just hope it puts me in a house I’d want.”
"Yeah. Anything else you want to know and don't yet because of being Muggle-born? I don't know how much they tell you in your versions of the letter."
“Well, nothing really springs to mind immediately. I have trouble thinking of something I don’t know unless it becomes noticeable that I’m missing something.”
"Okay. You can ask me if you want, I know enough about Muggle things not to be confused. Probably, anyway. It's going to be really different, Muggle London and wizarding London are more different than Muggle London and Muggle Melbourne."
Matt wonders what to say in reply to the other part. He’s never been good at making conversation. The result of this is that he doesn’t say anything else in reply.
Miranda apparently isn't that great at making conversation either, or she's done trying for the time being. She pulls out One Thousand Magical Herbs and Fungi and starts reading from a bookmark partway in.
They’ll probably stay like this until the Food Trolley arrives.
"Be careful of the Every Flavor Beans," she warns Matt. "Sometimes 'every flavor' is chocolate, but sometimes it's sawdust, or worse."
Matt looks confusedly at the chocolate frogs. “Those aren’t living frogs made of chocolate, are they?”
"No, they're just enchanted to move around. They're really tasty. You can have one of mine if you don't want to buy six."
He declines to buy anything from the food trolley himself.
Miranda offers him a frog.
Smiling slightly, he takes the chocolate frog, bites it, seems to deem it palatable, then sets about eating the rest.
