Once upon a time, there was a little mouse. The mouse lived in a big house. The house had many expensive things. The mouse liked to play with the expensive things.
One day, the mouse saw a big cat. The cat said, "Mouse, do not touch the expensive things!" The mouse was scared of the cat. The mouse said, "I will not touch the expensive things."
The cat went away. The mouse wanted to play with the expensive things. The mouse touched an expensive thing. The cat came back and saw the mouse. The cat slapped the mouse. The mouse learned not to touch the expensive things.
