Once upon a time, there was a delicate lock. It was silver and shiny, and looked very special. One day, a little girl wanted to open the lock to see what was inside. She shook it, but it wouldn't open! She tried to pull it, but it was too hard.
Then, one day, the girl's mommy came in and said, "Let me try". She held the lock and felt it. She smiled and said, "I know what will open this lock" and reached out for a small tool. She used the tool to carefully push a button on the lock and it made a CLICK.
The little girl was so excited and said, "Oh, it opened! What do we have inside?” Inside the lock were two bags of candy! The little girl ate a few pieces, but the mommy said, "No, don't spoil yourself. Save some of the candy for later, okay?” 
The little girl hugged her mommy and said, "Of course!" She put the candy back inside the lock and said, "Oooh, this is very special". 
And from that day on, the little girl and her mommy saved the candy inside the delicate lock, so the little girl could have a special treat every once in a while.
The end.
