If you get knocked down by a car, do you care what colour it is?

Strange title for a blog post I know, but I have a question and I’d appreciate some feedback.

My books typically deal with the end of the world in one way or another, but I’m generally more interested in how people deal with whatever’s happened to them than with the cause of ‘the event’ itself. If you were trying to survive through an apocalyptic scenario, let’s say (very topically) a pandemic, would it really make any difference to your struggle if the killer disease was man-made, a naturally occurring mutation or something of alien origin? This brief extract from AUTUMN summarises the point I’m trying to make:

‘So do you think it was a virus that did this to them?’ Carl asked. ‘Emma seems to think so. Or do you think it was…?’

‘Don’t know and I don’t care.’

‘What do you mean, you don’t care?’

‘What difference does it make? What’s happened has happened. It’s the old cliché, isn’t it? If you get knocked down by a car, does it matter what colour it is?’

‘Suppose.’

‘It doesn’t matter what caused any of this. What’s done is done and I can’t see the point in wasting time coming up with bullshit theories and explanations when none of it will make the slightest bit of difference. The only thing that any of us have any influence and control over now is what we do tomorrow.’

My question to you, however, is this: as the reader of a post-apocalyptic story, how important is it for you to know what happened? Do you need to know what caused the virus in AUTUMN? Will it spoil your enjoyment of the HATER trilogy if you don’t find out why people are suddenly turning on each other?

Any feedback / comments / thoughts from anyone would be appreciated. Please use the comments function and the related forum discussion to let me know.

Thanks in advance!
