The world has grown small and irritating recently, and the noises from elsewhere are increasingly compelling. Your kicks and stretches have no more room to relieve your cramped frustration. It's time to show the world who's boss: you. You are the boss. You kick and kick and peck and kick, and some part of the world finally gives. You stick the tip of your beak outside the small hole you've chipped and scream really loudly. Whatever is outside the world has now been put on notice! You're going to kick your way out of this used-up, brittle world and then just keep kicking whatever else is out there to kick.
