標題：The Fallen Leaves

Autumn is a magical season, with the leaves changing colour and falling to the ground. I often go for walks in the park and watch the leaves fall, feeling the crunch under my feet as I walk. But what I love most about the falling leaves is how they create a beautiful carpet of yellow and orange, which covers the ground and adds a beautiful touch to the scenery. I also enjoy how they remind me of how life cycles, as they fall to the ground and eventually decay, providing nutrients for the soil and creating new life for next year"s leaves to grow from. The falling leaves are a beautiful reminder of nature"s cycles and the beauty of life.
