When I was young, I watched the story of the boat carving to seek the sword and thought that the man from Chu was so foolish. How could the sword that fell into the lake be found on the shore? I laughed at him for never being able to retrieve the sword in his lifetime. It wasn't until I grew up that I understood, in the long river of time, how many people repeatedly return to a certain point, wanting to find what they have lost, but can only linger by the boat of memory, for what is lost will never return, because you are no longer the you that you once were.
