Punctuation? Who cares?

Cormac McCarthy left a lot of questions unanswered in this cold, depressing story. There are really only two characters, both remain nameless. We don't know their exact ages, nor where they came from, only that they are heading south.

The grammatical style matches this lack of detail. If I had handed in English language homework with so little punctuation and such lack of conventional sentence structure, it would have been handed back to me covered in red ink and with zero out of ten.

But none of this matters. It certainly wouldn't matter if the world as we know it had ended. The only thing that matters is how you would act if you were in this man's shoes.
