"Oh. Well, they've got lots of stuff more impressive than wall clocks and parking meters."

"Oh, aye, but wizards use wall clocks, too, an' it was muggles who made 'em. Lotsa stuff was muggles! Gets some folks right mad, that."

"Why would that make people mad?"

"Lotsa people don' really like muggles."

"...Why?"

"'Cause they don't have magic, I reckon. An' they think wizards n' witches who had muggle parents are less good, but they're wrong. Your mother was one o' those, and she was the best witch o' her time."

"That's incredibly stupid. How many witches and wizards even are there?"

"Dunno about all the world, but—ev'ry year Hogwarts gets about forty new students, an' that's from all o' Great Britain. Some people homeschool but not many."

"That's tiny. Of course we--they--invented almost everything, they're almost all the people."

"Aye, an' some folks are mad about that."

"That's really stupid."

"Aye. 'S what..." He looks around. "'S what You-Know-Who was about, tryin' ter get muggles an' muggleborns gone."

"...Gone?"

"Aye. Yeh know..." Pause. "Dead."

"And it didn't occur to them that murdering almost literally everyone in the world would be a bad idea?"

"I reckon he was only focusin' on Great Britain, an' maybe he jus' wanted ter conquer muggles an' not let 'em marry wizards, but who knows."

"Oh, that makes more sense."

They continue walking through the little town, and passersby stare a lot at Hagrid as they do, both due to the fact that he's twice as tall as anyone else and due to comments like those about parking meters.

Reasonable.

Soon they teach the station. There's a train to London in five minutes' time and Hagrid, who doesn't understand "Muggle money," gives the bills to Dorea so she can buy their tickets.

Dorea is competent to buy them tickets!

People stare more than ever on the train. Hagrid takes up two seats and sits knitting what looks like a canary-yellow circus tent. 

"What's that?"

"'S a sweater."

"Is knitting fun?"
