 
Once upon a time, there was a little train. Its engine was old and loud, but the little train was very happy with it. Every day it would meet all the other trains on the railway, and they would talk and share stories. But one train was very envious. It was brand new and had a much better engine than the little train. It wished that its engine could be just like the little train's engine.
One day, the little train’s engine broke down. It couldn’t move. The envious train was thrilled. It thought this was the perfect chance for it to get its wish. It slyly suggested to the little train that it should switch engines.
But the little train answered, "No thank you. Even though my engine is old, it is still my best friend. We can't switch."
The envious train was so surprised. It had never had a friend like that before. It quickly made a new friend with the little train and they have been friends ever since. The little train taught the envious train that there is more to friendship than having the best engine.
