"I love you."
"Sorry, what was that? Actually, give me a second. I just need to finish writing up this report on Crumple-Horned Snorkacks … there we go. What were you saying?"
"I love you."
"Are you sure? Because sometimes Wrackspurts can float into your brain and make you think that –"
"No. It's not the Wrackspurts. I love you."
"What makes you think that?"
"I'm not really sure."
"Well shouldn't you be sure before you say it?"
"I am sure; I'm just not sure why."
"You're not being very logical, you know."
"Do I need to be?"
"Not particularly, but most people are inclined to insist on proving that things exist before they believe in them. Can you prove you love me?"
"No, I suppose not. I can't prove I don't, though. And you've always said that anything can be true if nobody's –"
"– if nobody's ever proven that it's not."
"Exactly. And I love you."
"Well in that case I suppose I love you too."
