Once upon a time, there was a little girl called Sally. Sally was three years old and loved to play in the park. 
One day, Sally was playing in the park when she stumbled across a strange sack lying in the grass. Sally picked up the sack and shook it. Something inside made a hard noise. 
Curious, Sally asked, "What's in the sack?" 
A voice answered, "Food!"
Sally smiled and opened the sack eagerly. As the sack opened, she found lots of yummy food inside. Sally ate until her tummy couldn't take any more.
Little did Sally know, this sack belonged to the old magic woman who lived nearby. Every time she saw a person who was kind and helpful, the magic woman filled her sack with food. 
Sally had been kind and helpful to her friends in the park that day, so the magic woman rewarded Sally with a sack full of food. 
Sally was happy and felt like a reward for being kind!
