Adapting for Audio: Shoo, Fly - the introduction

Since I'm adapting some of my short stories into audio dramas for A Flame in the Dark, I thought it might be fun to chronicle some of the differences and similarities in writing for the two formats. In this case, I'm adapting my short story "Shoo, Fly" (available now as part of the 'Zine Killers collection) into a miniseries. Though I'll be adding quite a bit in the way of action and even characters to the series itself, I'm cutting quite a lot out of the narration. As you might expect, narration for readers is a far different animal than narration for listeners. 

So, as an example, here's an excerpt from the opening narration of the short story:

I don't want to speak for what's left of humanity. I have no idea how they thought the world was going to end. Or even if they thought about it at all. If they did, I imagine they thought pretty much along the same lines as I did: A World War III nuclear blast scenario, a fast-acting pestilence -- hell, a zombie apocalypse. But I do guarantee that nobody -- not the Mayans with that calendar they always talked about on the History Channel, not those Nostradamus freaks, not the Nike-wearing Koolaid-drinkers who waited for that comet -- believed that the kingdom of man would be destroyed by houseflies. 

And here are the opening lines from the audio drama:

NARRATOR:
It’s safe, I think, to say nobody expected humanity to go out this way. Global warming. Natural disasters. All-out thermonuclear heck. Zombies, even. I think I personally expected Wrath of God, but I could have handled zombies. I mean, I’d have been alright with it.

But this? This just feels… stupid. 

I'll be adding more as the adaptation continues. Thoughts? Too many changes? Just enough? Let me know in the comments!
