We wrote the first draft in about nine weeks. Nine weeks of gloriously long phone calls, in which we would read each other what we'd written, and try… - Neil Gaiman

Fairy tales are more than true: not because they tell us that dragons exist, but because they tell us that dragons can be beaten.

"I mean, d'you know what eternity is? There's this big mountain, see, a mile high, at the end of the universe, and once every thousand years there's this little bird-"
-"What little bird?" said Aziraphale suspiciously.
-"This little bird I'm talking about. And every thousand years-"
-"The same bird every thousand years?"
-Crowley hesitated. "Yeah," he said.
-"Bloody ancient bird, then."
-"Okay. And every thousand years this bird flies-"
-"-limps-"
-"-flies all the way to this mountain and sharpens its beak-"
-"Hold on. You can't do that. Between here and the end of the universe there's loads of-" The angel waved a hand expansively, if a little unsteadily. "Loads of buggerall, dear boy."
-"But it gets there anyway," Crowley persevered.
-"How?"
-"It doesn't matter!"
-"It could use a space ship," said the angel.
Crowley subsided a bit. "Yeah," he said. "If you like. Anyway, this bird-"
-"Only it is the end of the universe we're talking about," said Aziraphale. "So it'd have to be one of those space ships where your descendants are the ones who get out at the other end. You have to tell your descendants, you say, When you get to the Mountain, you've got to-" He hesitated. "What have
they got to do?"
-"Sharpen its beak on the mountain," said Crowley. "And then it flies back-"
-"-in the space ship-"
-"And after a thousand years it goes and does it all again," said Crowley quickly.

There was a moment of drunken silence.

-"Seems a lot of effort just to sharpen a beak," mused Aziraphale.
-"Listen," said Crowley urgently, "the point is that when the bird has worn the mountain down to nothing, right, then-"

Aziraphale opened his mouth. Crowley just knew he was going to make some point about the relative hardness of birds' beaks and granite mountains, and plunged on quickly.

-"-then you still won't have finished watching The Sound of Music."

Aziraphale froze.

-"And you'll enjoy it," Crowley said relentlessly. "You really will."
-"My dear boy-"
-"You won't have a choice."

Have you ever been in love? Horrible isn't it? It makes you so vulnerable. It opens your chest and it opens up your heart and it means that someone can get inside you and mess you up. You build up all these defenses, you build up a whole suit of armor, so that nothing can hurt you, then one stupid person, no different from any other stupid person, wanders into your stupid life...You give them a piece of you. They didn't ask for it. They did something dumb one day, like kiss you or smile at you, and then your life isn't your own anymore. Love takes hostages. It gets inside you. It eats you out and leaves you crying in the darkness, so simple a phrase like 'maybe we should be just friends' turns into a glass splinter working its way into your heart. It hurts. Not just in the imagination. Not just in the mind. It's a soul-hurt, a real gets-inside-you-and-rips-you-apart pain. I hate love.
