One sunny afternoon, Sara was playing in her backyard. She loved running around the garden, chasing butterflies.

 While running, she suddenly spotted a small, shiny object on the ground. It was a key! Sara picked it up and wondered where it came from.

She looked around but didn't see anyone nearby. Perhaps the key belonged to someone in her neighborhood. Curious, Sara decided to find its owner.

First, she walked to her friend Tom's house and asked, "Tom, do you know whose key this is?" Tom looked at the key and shook his head.

"I don't know," he said.
