It's four perfect paragraphs, so try to pencil in a reading.
Here's a taste:
Knowing that you’re doing something for the last time is a uniquely human fear. I thought that would be the hardest thing about having pigs. In fact, it’s not so hard, though it does remind me that humans have trouble thinking carefully about who knows what. One day soon I’ll step into the pen and give the pigs a thorough scratching, behind the ears, between the eyes, down the spine. Their tails will straighten with pleasure. It will be the last time. I will know it, and they simply won’t.
