A little boy who was going uphill with his father hit his foot on a stone and said, "AAAAH!" screamed out of nowhere and AAAA! When he heard the sound, he was surprised and asked, "Who are you?" "Who are you?" he shouted, "Who are you?" He got angry and said, "You are a coward," and when he heard that you are a coward, he said, "What is going on, father?" asked. His father smiled and shouted, "Listen carefully, I respect you." In response, he replied, "I respect you, you are the best, and you are the best." The father said to his surprised son, - It is called an echo, and it can also be called life. Because life is like an echo, what you say and what you do is reflected back to you.
