One day, a little girl named Lisa was playing in her room. She saw her big bookcase full of books. On top of the bookcase was a big orange ball. Lisa wanted to play with the orange ball, but she was too small to reach it. She called her mom for help.
"Mom, can you help me get the orange ball?" Lisa asked. Her mom came into the room and saw the ball on the bookcase. "Okay, but you must promise to put it back when you are done playing," her mom said. Lisa promised and her mom got the ball for her.
Lisa played with the orange ball all day. She threw it, kicked it, and rolled it around. But when it was time to put the ball back on the bookcase, she found that the bookcase was now empty! All the books were gone! Lisa was very surprised. She didn't know what happened to the books. Then, she saw her little brother in the corner, giggling. He had taken all the books out to make a fort. Lisa laughed and they played together in the book fort. The orange ball remained on the floor, waiting for the next playtime.
