I wonder if the tree feels sad...sad when the leaves go away... fall... How do they part? Does the leaf send a signal? A chemical that starts the pushing away? Or the tree to the leaf? Do they prepare each other for their inevitable separation? And what about the joy in spring? When the weather changes again and the buds begin to sprout... As pregnant as she is with life, does the tree feel the pain, the joy as new life springs forth? And when the leaves come again...do they need just a little time to get to know each other again?
