Once upon a time, a mouse gave birth to a baby mouse and the snake gave birth to a serpent. The mouse prohibited its baby from playing at the brook near his house, lest he drowned and died. One day the baby mouse and the serpent met, and became friends and played together. In the evening when they finished playing, both the baby mouse and the serpent went to their mothers. When the baby mouse got home, his mother remarked that his hair was wet and she spoke to him harshly. Mother Mouse: Did you go to play at the brook that I forbade you from going? Baby mouse: No, I did not go to the brook. Mother Mouse: Then how come you are so wet? Baby mouse: It’s the saliva of my friend serpent that made me wet. Mother Mouse: Listen very carefully! Since the time of our ancestors, snakes have never been our friends. They still consider us their favorite food.
