The ice in the Hyatt hotel bar dropped into the metal bin every few minutes, sharp and hollow, keeping time with a night that had already gone off the rails. I am sixty-one years old, and I have taught Sunday school in Muncie for nearly three decades, which means I know the exact distance between a mistake and a sin. That night in Columbus, sitting by a fake stone fireplace with club soda and stale pretzels, I crossed a line I always told myself was uncrossable.
