A boy holding his smart phone in hand asked his mom:"why should I go to school while I can get all knowledge from my smart phone?""You silly boy," replied his mother, "Your teacher teaches you what kind of knowledge you have to learn and what you shouldn't. Most importantly, you learn how to be in the society by making friends in the school. Otherwise how can you find your girlfriend in the future?"
