When the wind blows a leaf off its branch, it traces a crooked path through the air before accelerating toward the ground. It doesn't know where it will go next, but I do: summer is over. The leaf will never return to the treetop. It may be swept away by the wind or carried off by the rain, entering a long, withered night.
"Summer is over. In Japanese, the phrase means growing up overnight. It foreshadows a love that ends without ever beginning. It is the season when youth fades away, the dividing line between dreams and reality, the night you lose your innocence and become an adult, and the moment life falls from an exciting unknown into an unchangeable sense of helplessness." -- From the encyclopedia
