 
Once upon a time there was a little boy named Tim. He was three years old and loved playing jokes on his family. 
One day he found a lock in his mom's room. He thought it would be funny to try and lock his mom inside. So he did it! But when his mom tried to open the door, she couldn't. 
His mom got very angry with Tim and said, "Tim, why did you do this? This is not a funny joke!" 
Tim felt guilty. He didn't mean to make his mom so mad. He said, "I'm sorry, Mom. I just wanted to pretend that you were stuck in a jail cell." 
His mom looked at Tim and said, "Well, I understand, but you still shouldn't have done it. Next time you want to play a joke, tell me first, okay?". Tim nodded his head in agreement. This time, he knew better.
