The narrator finds a single red leaf that had blown onto their face on a windy fall day. They observe the leaf closely and reflect on its life cycle, from providing shade and shelter in spring and summer to ending its life beautifully in autumn. The leaf reminds the narrator that even one small thing can do much good, and inspires them to live their own life to the fullest by helping and giving comfort to others. The document encourages the reader to share their beauty with the world and commit to living fully each day.
