One day, a boy named Tim found a heavy rock. He liked the rock and wanted to take it home. He picked it up and carried it with him. But the rock was very heavy, and it made Tim very tired.
On his way, Tim met his friend Sue. She saw the heavy rock and said, "Tim, why are you carrying that heavy rock? It looks too big for you." Tim replied, "I like this rock. I want to take it home."
But after a while, Tim started to regret carrying the heavy rock. It was too much for him. He said to Sue, "You were right. This rock is too heavy for me. I wish I had listened to you." Sue smiled and said, "That's okay, Tim. We all make mistakes. Let's put the rock down and go play together." So they left the heavy rock and had fun playing for the rest of today.
