She's a four-year-old girl, and people (especially her Dad) insist she's a boy.
Not that she isn't sometimes. She is. But not today! Today she's a girl. And Dad keeps saying that's not true, that God made her body perfect and she shouldn't second-guess God's plan for her. God made her a boy, so she's supposed to be a boy. And on the one hand that kinda makes sense. God doesn't make mistakes, right? So if she were really a girl sometimes, then she'd... what? Her body would change, she guesses. But on the other hand, she knows she's a girl. She's a girl with a peepee, that's obvious. She'd prefer not having a peepee when she's a girl, but it's not the worst thing ever. And if God doesn't make mistakes, God also didn't make her feel like a girl sometimes on accident, right? It must be part of His (because God is always a He, even though God made everyone, boys and girls, in His image, he's always a He, Dad says) plan.
She tells Dad that, today, and Dad gets angry, and yells at her, and she doesn't know why he's yelling. It makes sense to her! But he won't explain why she's wrong, he's just yelling, Dad's so mean, she hates him, and she's not crying, shut up, you're crying!
And now Mum's coming and she's talking to Dad, and that usually makes Dad stop yelling and go away but he won't stop now and Sadde's angry and afraid and hurt and she's running away. A part of her thinks that it doesn't make much sense to run away, the park is pretty open and she can't really hide anywhere, and she'll have to go back because she'll get hungry (not now, though, she just ate a sandwich).
So she runs until she finds some bushes where she can hide, and she hides there, and she doesn't cry, and she spends a long time not crying. Mum and Dad don't come after her, though, and after she's done not crying she doesn't wipe her eyes and her nose, and she comes out the other way of the bushes she was hiding in.
And she's pretty sure that's not the park.
"I don't want to be a vassal," he mumbles weakly, because he still doesn't really know what a vassal is and this nice fairy lady is offering him books. About magic.
"Not really fire. Hydrogen. It's a tiny tiny element, the smallest of them all, and there's nu... nu..."
"That! There's nuclear fusion going on all the time, and the hydrogen gets... like all together with other hydrogens and becomes all sorts of other elements!"
"And I'm sure we could reach an arrangement about that. We don't have books about magic, you don't have books about physics, so we'll trade."
She starts circling them, weighing them with more seriousness and interest than before. "But why settle for only one thing? You could have it all. You could have your books there, and our books here, and you could be with us. All I would need is your name." She flies closer to Laura and holds her chin. "You're young, but I could keep you that way forever. I could make you look however you want."
