One day, the rabbit was writing in front of a cave, and a wolf came up and asked, "Rabbit, what are you writing?" The rabbit replied, "I'm writing a paper." The wolf asked again, "What topic?" The rabbit replied, "I'm writing about how rabbits eat wolves." The wolf laughed and said he didn't believe it. The rabbit said, "Come with me." Then he took it into the cave and the rabbit continued to write in front of the cave. Then another fox came over and asked, "Rabbit, what are you writing?" The rabbit replied, "I'm writing a paper." The fox asked, "What topic?" The rabbit replied, "How does the rabbit eat the fox?" The fox laughed after hearing this, expressing disbelief. The rabbit said, "Come with me." Then he took it into the cave. After a while, the rabbit went out of the cave alone and continued to write his paper. At this time, in the cave, a lion was sitting on a pile of bones and picking his teeth, while reading the rabbit's paper: the ability of an animal is not determined by its strength, but by who is the boss behind it.
