One day, a monkey became friends with a parrot. The parrot proudly said, “I can talk like a human!” The monkey was surprised and said, “Then why don’t you teach people?” The parrot thought for a moment and replied, “If you want to teach, you have to learn a lot yourself first!” The monkey laughed and said, “You can talk so much, you can definitely teach.” Then the parrot shook his head and said, “But if you study, you have to take exams, and I am very afraid of exams!”
