The world is rated R, and no one is checking IDs. Do not try to make it G by imagining the shadows away. Do not try to hide your children from the world forever, but do not pretend there is no danger. Train them. Give them
sharp eyes and bellies full of laughter. Make them dangerous. Make them yeast, and when they’ve grown, they will pollute the shadows.
