"I think it was a bit of an overreaction, to be honest," said the serpent. "I mean, first offense and everything. I can't see what's so bad about knowing the difference between good and evil, anyway."

"They just said, Get up there and make some trouble," said the serpent, whose name was Crawly, although he was thinking of changing it now. Crawly, he'd decided, was not him

"Yes, but you're a demon. I'm not sure if it's actually possible for you to do good," said Aziraphale. "It's down to your basic, you know, nature. Nothing personal, you understand."

"You've got to admit it's a bit of a pantomime, though," said Crawly. "I mean, pointing out the Tree and saying 'Don't Touch' in big letters. Not very subtle, is it? I mean, why not put it on top of a high mountain or a long way off? Makes you wonder what He's really planning."

"Best not to speculate, really," said Aziraphale. "You can't second-guess ineffability, I always say. There's Right, and there's Wrong. If you do Wrong when you're told to do Right, you deserve to be punished. Er."

They sat in embarrassed silence, watching the raindrops bruise the first flowers.
