Fat Man: Post-apocalyptic

Don't want to be a fat man, not in this world, not if you don't want to be followed home and all that's good taken from you. It's okay for the children, at least, thank goodness--everyone knows kids grow at different rates. Still, they need to stay "healthy" and not "chubby". But they can have enough to eat. Me and the wife? We have to stay a little too thin, no matter that if we wanted to we could each carry ten pounds extra. A cow giving milk and cream will do that, as will a damn fine mushroom crop in the basement. Why don't we share it with our neighbors? Well, they're so meat-starved they'd eat the cow, and then there'd be no milk for the children.
