She glances at Ron and hesitates. 

"...what? I won't get upset."

"...Girls are almost always more interesting than boys? Boys punch people and stick their heads in toilets and even when they're not the kind that does stuff like that they're just...they're not pretty like girls are."

"Punch people? That's—oh, I guess they don't have wands..."

"I mean I don't really care about pretty, I just am a boy today, and some days I just am a girl, and some others I'm neither."

"I'm not sure I understand."

"I—sometimes I don't feel like I'm a boy? And it feels weird and wrong to be one and to be shaped like one and I should be a girl and shaped like a girl and called a girl. But then sometimes it's the opposite. And sometimes it's something else."

"Huh."

"Yeah." Shrug. "So that's a thing."

"You learn something new every day."

"I can change other things, too." And his eyes pop out, shaped like a chameleon's.

He yelps.

She giggles.

He giggles and is back to regular human. "I can't turn all of myself into an animal, though. Just bits. Not my brain, for sure."

"Oh, gosh, I should hope not."

"It's not in principle impossible, there's a type of magic called animagic which makes you be able to turn into an animal and stay smart, but you don't pick which animal, it's personality-based or something, and a lot of work, and you have to be registered with the government."

"Huh."

"Don't think I'm gonna do it, though."

"Why not?"

"Takes a long time and doesn't seem like it's worth all the investment."

"I don't know, it sounds really cool."

"I can already turn into bits of animal, the benefit is only incremental."

"Well, it's a gamble, but--if you're a bird, or something small, there's absolutely benefit you can't get from bits. I'd really like being a bird, I think."

"...I suppose. But we can fly with brooms—but being small would be really cool."

"It would! Imagine being a cat, don't they look so comfortable?"
