The early morning sunshine had just shined into the small courtyard. I was combing the manes of the piglets in the pen when I heard a gentle knock on the door from outside the courtyard. When I opened the door, I saw a slightly bulky pregnant woman, struggling to hold a big fat pig standing at the door. The sow's hooves still had some old injuries. The pregnant woman said sincerely that the pig had accidentally hurt someone a while ago and was now wilting. She came here to ask for help, hoping to untie the pig's knot and make it docile again.
