Here's a short story:

The kids were playing outside. They were drawing with chalk. They drew many things with the chalk. One of those things was a star. There was nothing else for them to do because it was the weekend. Then they stopped drawing with the chalk a little later. They did not want to go on because they were tired. They walked a little then started to splash by the lake that was nearby instead. They thought it was a good idea because it was a hot day. They played for hours. They were making a lot of noise and laughing and talking. They went home. They did this because they were very tired. They all ate some bread. They were now quiet. They couldn't have anything else to eat until their mother called them for dinner. They waited and did not say a word. They were resting. Soon it would be time for the family meal. (End of story)
