The past needs to stay in the past. People don't need reminders from others of what happened way back when. Constantly bringing up past mistakes gets us nowhere. People who desire to change do change, and they shouldn’t be dragged down by the ghosts of the past. A person has no problem remembering regrets on their own without having to be reminded by someone else. Nothing is more frustrating than doing something right and having someone say that you used to do it wrong. What we do from today on matters, yesterday is long gone and those that don't want to live in the present need to be left in the past.
