Boar and sow: Once upon a time, there were two pigs, a male and a female. The boar always guards the sows at night because he is afraid that his master will pull them out and kill them while they are sleeping. As the days passed, the sows gradually gained weight and the boars became thinner day by day.

One day, the boar suddenly heard the owner discussing with the butcher to kill and sell the growing sow. The boar was extremely sad, so from that day on, the boar's temperament changed greatly. Whenever the owner brings food, the boar always rushes up and eats it completely. After eating well every day, he lay down to sleep and told the sow that it was her turn to keep watch. If he finds out that she is not on duty, he will never talk to her again. As the days passed, the sow felt that the boar cared less and less about her. The sow was disappointed, but the boar lived a stable life as if nothing had happened.

Soon, a month passed, and the owner took the butcher to the pigsty. He found that a month ago, the fat sow had little meat left, but the boar was shining. At this time, the boar ran desperately to attract the owner's attention and show that he was a healthy pig. Finally, the butcher took the wild boar away. The moment the pig was dragged out of the pigsty, the boar smiled and said to the sow, "Don't eat so much in the future." The sow was heartbroken and rushed out desperately, but the fence door had been closed by the owner.
