The Robot and the Bluebird

There was once a robot with a broken heart, expiring slowly on a scrap heap. Then one winter's day a migrating bluebird lands on his shoulder, too exhausted to go further. The robot offers her shelter in the place where his heart used to be. The bird's companionship stirs up the robot's last glimmer of energy and he carries her across snowy wastes to the warm south, whereupon his strength finally dies out. And there he stands today like an old hollow tree, home to singing birds.
