Lamenting their pathetic lives as they neared their starved deaths. He could smell the piss by the corner where they'd all mutually agreed to designate the bathroom.

He hoped he'd be the first to go.

Poor fools.

Didn't anyone wonder how they were breathing, trapped in this container? Follow the air. That's your way out, my fellow citizens.

But that knowledge isn't for you to know.
