Once upon a time, there was a little boy named Tim. Tim was a weak boy but he loved to play and explore. One day, Tim went into the kitchen and saw a big refrigerator. He wanted to open it and see what was inside.
Tim's mom saw him and said, "Tim, I warn you, don't open the refrigerator alone. You are too weak to hold the door." But Tim did not listen. He opened the refrigerator door and it was very heavy.
Suddenly, the door fell on Tim and he cried. His mom came and helped him. She said, "I warned you, Tim. Next time, listen to me." Tim learned his lesson and always listened to his mom after that.
