"I don't think you had much of an effect on her one way or another. People who'll take any outcome as a sign they're right will take any outcome as a sign they're right unless a choir of angels descends from heaven to sing them a little song about how wrong they are."

"Do you know where to get choirs of angels?" asks Bella.

"Sadly, no."

"That would be really useful. If you could call down choirs of angels to sing wrongness at wrong people," sighs Bella.

"It would probably cause more problems than it solved. But it's a nice thought."

"Heart attacks. Bewildered scientists. Copyright claims on the little songs."

She giggles.

"And the news would never shut up about it, either, it'd be all choirs of angels all the time, and I bet there would be silly cults."

"So many silly cults."

"And probably some really stubborn people wouldn't even believe they were wrong if an angelic choir told them so," sighs Bella, picking at a frayed spot on the hem of her jeans.

"Probably."

"I wonder what that is like. I wonder if it is so much like not being wrong that I couldn't even tell. Maybe I am wrong a lot about a lot of things and I can't notice no matter how hard I look."

"It's possible," she agrees. "But mostly, if you're trying, you can eventually tell. People who are like that are trying really hard not to tell, because it's more important to them to feel like they're right, or have everybody agree that they're right, than to actually be right. Or because they're just so sure about something that they can't face being proved wrong."

"The thing I look at most is me. I wouldn't want to be wrong about me. Then I wouldn't even know who was driving." Bella taps her head to indicate what is being driven.

"If I ever catch you being wrong about you, I'll let you know."

"Will you sing me a little song?"

"I don't actually know if I can sing."

"Row, row, row your boat, gently down the stream," begins Bella, in a voice that is well within human average.

Elizabeth giggles.

"Gently down the - You're not gonna sing? It's a round."

"I don't sing. Which is why I don't know if I'm any good at it, and also probably why I don't know what a round is."

"You don't wanna find out, either?" asks Bella, puzzled but not pushy. "A round is when everybody sings the same thing but offset - if you were going to sing you would have started with the rowing line when I started the gently line."

"Well, now I know what a round is."

"Yeah. Most of them are nursery rhyme type things like Row Row Row Your Boat."

"Aha."
