Look out there. Can you feel them? Incredible to think - other human beings out there. You strain your eyes the whole day long, see nothing, hear nothing, still can't believe it somehow - but know it's true. Other warm bodies, hearts pumping blood. That ought to make us feel less lonely, or safer, it seems. Then why is it so shocking? Because - they don't belong here. The possibility of life in this place is more terrifying than the place itself. Can it be that we're really here?

Everything is a tool - a boot, a sled, a dog - and a hand, an arm, even a man! If it breaks down you throw it away and you march on! It's brutal, yes! And it's ugly. But anything else is sentiment and it will kill you.

Playing the game means treating your dogs like gentlemen, and your gentlemen like dogs.
