Leo always enjoyed visiting his grandparents' house, especially during the summer. Their backyard was a lively place filled with flowers, birds, and a small vegetable garden. One afternoon, while playing outside, Leo found a small, shiny object buried in the ground. Curious, he dug it up and discovered it was a key. Leo wondered what the key might unlock. Excited about his discovery, he ran inside to show his grandparents. They smiled and told him, 'That key might be very important!' Leo felt a sense of adventure thinking about all the possibilities.
