"I'm sure it's someone," said Jon, "but like I said it doesn't matter. Sarah didn't specify why we have children. So I can make a wish that says the father is anyone we want. We could even come up with some kind of sci-fi explanation."
"I know," said Karyn, "but still. It could be interesting."
"It doesn't matter," said Jon. "Besides, it isn't really whoever Sarah's wish made it be. People just think it is. We just need to decide... who do you want it to be? Let's make that wish right now. Explain away our childrens' parents."
