“
I have lived in this tree, in this same hollow," the owl said, "for more years than anyone can remember. But now, when the wind blows hard in winter and rocks the forest, I sit here in the dark, and from deep down in the bole, near the roots, I hear a new sound. It is the sound of strands of wood creaking in the cold and snapping one by one. The limbs are falling; the tree is old, and it is dying. Yet I cannot bring myself, after so many years, to leave, to find a new home and move into it, perhaps to fight for it. I, too, have grown old. One of these days, one of these years, the tree will fall, and when it does, if I am still alive, I will fall with it.
