Scenario is you wake up one morning and no one is there, no wife, no parents living above the basement, no flatmate (whatever the situation).
There are no bodies lying in the street, no wreckage of cars etc, everyone is just gone.
TV is out etc. You have no idea what has happened, you have no idea if there is anyone around in the world, but after a comprehensive search there is no one in the neighbourhood.
Neighbourhood pets are gone, but wildlife is still about.
What would you do?
I would probably not realise for most of the day that I am on my own. Seriously my powers of observation are often so limited that I just trudge my way along.
After I realised that everybody is gone, and it just me left well, the possibilities are endless aren't they? After all who is there to stop you? But then again, I reckon before that you'd be consumed trying to find your loved ones.
