Every one of my friends had a bad day somewhere in her history she wished she could forget but couldn't. A very bad mother day changes you forever. Those were the hardest stories to tell. . . . "I could still see the red imprint of his little bum when I changed his diaper that night. I stared at my hand, as if they were alien parts of myself . . . as if they had betrayed me. From that day on, I never hit him again."
