Tim and Lily were playing in the garden. They saw a big vine that grew on the wall. It had many green leaves and purple flowers.
"Let's climb the vine!" Tim said. "It looks like fun!"
Lily was not sure. "But what if we fall? Or what if Mom and Dad get angry?"
Tim shrugged. "Don't be scared. They won't see us. And the vine is tough. It can hold us."
He grabbed the vine and started to pull himself up. Lily followed him, but she felt nervous. The vine was high and wobbly.
They reached the top of the wall and looked around. They saw the neighbor's dog, a big and black one. It barked at them and ran towards the wall.
"Uh-oh!" Tim said. "The dog is mad at us! We have to go down!"
They tried to slide down the vine, but it was not easy. The vine was rough and scratchy. It hurt their hands and legs. The dog jumped and snapped at them.
"Help!" Lily cried. "Mom! Dad!"
Mom and Dad heard them and came outside. They saw Tim and Lily on the vine and the dog on the ground. They were shocked and worried.
"Tim! Lily! What are you doing?" Mom shouted. "Get down from there!"
Dad grabbed a stick and scared the dog away. He helped Tim and Lily down from the vine. They were dirty and bleeding.
Mom hugged them and checked their wounds. She was angry and sad.
"Why did you climb the vine?" she asked. "You could have been hurt badly! Or bitten by the dog! You know you are not allowed to do that!"
Tim and Lily looked down. They felt sorry and ashamed.
"We wanted to have fun," Tim said. "We thought the vine was tough."
"But it was not safe," Lily said. "We were wrong."
Mom and Dad took them inside and cleaned their wounds. They gave them a hug and a kiss.
"We love you, Tim and Lily," they said. "But you have to be careful and listen to us. We only want you to be safe and happy."
Tim and Lily nodded. They learned their lesson. They never climbed the vine again.
