One day, the Pig asked the Farmer why she was kept in a pen.
The Farmer said, "Because I love you very much, I have put up this fence to protect you from those who would harm you."
The Pig blushed and said, "Why do you love me?" and the Farmer said,
"Because without you, I would die. You give me the energy to live, and the meaning to my life."
The Pig laid down in her plot of mud and smiled, knowing that she gave life and meaning to the Farmer; and she was happy the rest of her days.
