Do not wallow in your mistakes. Do not grovel and prostrate yourself in hopes of forgiveness. We all make mistakes. Apologize and move forward. Do not replay the event in your head. Do not continue to beat yourself up. Do not profusely explain, defend yourself, make excuses or blame. After you apologize, do no more explaining; never explain more than once — ever.
