Ben Winston's haunting short story, "Invincible".
Before the heat of shame works its way to my fingertips, the intruder’s stall falls silent. My body tenses, and I sense Mikey’s does too. Long moments pass. An eternity. My lungs scream. Then a long exhale comes, slow and continuous. I imagine the man’s body deflating, the air from every corner of his body pouring out of his mouth, leaving his skin cinched tight around his skeleton like a mummy. The exhale fades out and I hear the soft creak of the toilet seat, followed by two loud thuds.
