My dad used to tell me, "Hank, you'll never go anywhere if you're staring at the rear view mirror." Yes, the past can hurt. But the way I see it, you can either run from it or learn from it. (name that quote!)

If there is someone in your life (including yourself) who is trying their best to change, let them repent. Promise them you'll help them bury it by never bringing it up again.
