Locked,, just like your heart. You don't share your feelings, you kept them locked. And the dead leaves echoed the sound of Andrea Bocelli singing " Mais la vie separe, Ceux qui s'aiment, Tout document, Sans faire de bruit.."-- from his "the falling leaves" song. [Translation]: "But life separated, Those who loved, Very gently, Without making a sound..".. Those dead leaves are your locked feelings, the more you keep them inside your heart, the more you lose green leaves and your loved ones.
