 
Once upon a time there was a market. Every day people sold all kinds of things there. One of the vendors was an old lady. She sold coffee. 
One day a little boy visited the market. He had never been there before, so he was very excited. "What are you selling?" he asked the old lady. 
 
"Coffee," she replied. 
 
The little boy scratched his head. "What is coffee?" he asked. 
"It is a warm and healthy drink," she smiled. 
The little boy smiled back. He thought that sounded wonderful. Every day after that he visited the old lady and bought her healthy coffee. They became good friends. 
Soon everyone in the market knew the old lady's coffee was the healthiest around. The market became so busy that there was always a long line of people waiting to buy her coffee. 
 
The old lady always smiled. She was so happy that people loved her healthy coffee so much.
