Once upon a time, there was a little train. The train loved to run fast on the tracks. Every day, it would go through the town and make the people happy.
One sunny day, the train was running very fast. It was working hard to go faster and faster. Then, something unexpected happened. The train saw a big tree on the tracks. It was too late to stop!
But then, a little bird came and pushed the tree off the tracks. The train was so happy and thanked the bird. The bird smiled and flew away. From that day on, the train and the bird became best friends. The train learned that even the smallest friends can make a big difference.
