One morning, a father drove his two sons to school. On the way, the boys sat on the back seat, continually argue with each other about something. Finally, it became so heated that all boys grew annoyed. Quite disappointing, the father tried to calm them while driving. But it was uselessly. Soon, boys angrily kicked each other, making the father fail to focus on driving. He then turned back to stop from his sons. Just then, the car lost control but almost hit one of the vehicle coming in another direction. Since that day, the boys had never fought in the car, fearing affecting his father’s driving.

John went to shop but forgot to bring a shopping bag. But he bought one. Just then an idea struck him which he might use the old trousers to make the bag. He began to do it immediate he arrived home.

When asked what he felt about his creation, John replied: "This is the first time that I had such a wonderful experience."
