"Trading other things for them."

"Huh. Do you want it to rain? My water spirit friend said you might want it to rain."

"...That would be good. If it wasn't too much rain."

"How much rain is too much?"

He names a figure.

"I don't know if I can do that much before I get tired anyway."

"It makes you tired?"

"Doing magic? Kinda yeah."

"And the rain doesn't just keep going once you put it there?"

"I guess it depends on whether it would rain anyway at that point."

"Huh."

"I don't know, I've never actually done it."

"Then how do you know you can?" he asks, interested despite himself.

"It just seems like a thing I can do, like walking and talking and flying."

"Huh." He considers this, then sheathes the knife and puts it and the piece of wood in a pocket, stands up, dusts the wood shavings off himself, and starts walking toward a wooden building.

"Where are you going?"

"That's the barn," he says, pointing, "it has cows in it."

"Ooh, can I see?"

"Yep."

She follows him.

He opens the door and leads her inside. There are several cows and two horses in stalls.

"Oooh! Which ones are cows?"

He points at the cows. "And those other ones are horses."

Nod nod. "Why is it important to distinguish their ends?"

He snorts. "It's just a way of commenting on how little practical knowledge city slickers have."
