Tom and Lily were twins who liked to visit their grandpa's farm. Grandpa was an old farmer who had many animals and plants. He always let Tom and Lily help him feed the chickens, milk the cows, and water the flowers.
One day, Tom and Lily saw a big tractor in the barn. They wanted to ride on it and see how it worked. They asked Grandpa if they could, but he said no. He said the tractor was too big and too loud for them, and they could get hurt.
But Tom and Lily did not listen. They insisted that they could ride the tractor. They said they were big and brave, and they knew how to drive. They waited until Grandpa was busy with the pigs, and then they sneaked into the barn. They climbed on the tractor and pushed the buttons.
The tractor started to move and make a lot of noise. Tom and Lily were scared, but they did not know how to stop it. The tractor went out of the barn and into the field. It bumped into the fence, the scarecrow, and the haystack. It made a big mess and scared the animals.
Grandpa heard the noise and ran to the field. He saw Tom and Lily on the tractor and shouted at them to get off. He was very angry and very worried. He turned off the tractor and helped them down. He hugged them and told them they were very naughty and very lucky. He said they could have been hurt or broken the tractor.
Tom and Lily felt sorry and ashamed. They said they were sorry to Grandpa and to the animals and the plants. They said they would never insist on riding the tractor again. They said they would listen to Grandpa and be good.
Grandpa forgave them and told them he loved them. He said they could still help him with the farm, but only with the things that were safe and fun. He said they could ride on his old bike or his old horse instead. Tom and Lily agreed and smiled. They learned their lesson and enjoyed the rest of the day on the farm.
