"Yes. White isn't a usual color for human hair."

"Why not?"

"...Because people look like their parents, and the only available parents with white hair are spirits or magicians."

"Oh. I don't really understand parents."

"What do you know about them?"

"I know the words for them. A mother is a female parent and a father is a male parent."

"True. Alright, so the basic way that parents work is that a man and a woman can create a child together, and when they do they are that child's parents."

"Okay. Do people do that a lot?"

"Hm--do you mean does any one person do it frequently, or just does it happen in general frequently?"

"The second thing."

"Yes."

"Huh."

"There would be much less people around if we didn't."

"I don't really want to do that. I guess I'm different."

"Well, you're not human. And not all humans want to, anyway."

"Oh, okay."

"Sometimes they do anyway. It doesn't always end well."

"What do you mean?"

"Parents are supposed to love their children. Sometimes they don't."

"Why are they supposed to?"

"...Children do better with affection."

"Oh."

"And children mostly love their parents, and aren't emotionally mature enough to react well to unreciprocated love."

"Why do they love their parents?"

"Instinct."
