All of us have had moments in our lives that we wish we could do over, incidents from our past that gnaw at us in spite of our best attempts at repressing them - or sometimes, erasing them altogether - from our memories. When we say something hurtful we can't take back, or engage in behavior we know is wrong, even if it's a forgivable, human mistake. Some of our writers have volunteered to share their private shame. Please forgive them, and use the comments in this space to share your own absolutions.

Let the healing begin. First up, Kiese Laymon.
