Beast of Burden

Our beasts of burden are amazing. They understand commands, they transport us and our goods over any terrain, they can survive on cheap slurry. Sometimes we feel a little guilty, since we’re the same species. But we bred them to be bigger and dumber than us, and while they did get bigger, the dumber part didn't really take. When I went to the stables last night, they were in deep discussion, but went silent as soon as I entered. Since conversation is forbidden, they knew I’d take away their nightly slurry, yet seemed unfazed. I wonder what mischief they're planning?
