... Let the cage bird and the cage bird mate and the wild bird mate in the wild.
William Butler YeatsAll things uncomely and broken, all things worn out and old The cry of a child by the roadway, the creak of a lumbering cart, The heavy steps of the plowman, splashing the wintry mold, Are wronging your image that blossoms a rose in the deeps of my heart.
William Butler Yeats
