Scars

Why is it that the scars that we don't see are the hardest to heal. Is it because we can't apply peroxide or ointment to these sores. Why is it that as time goes on we forget the first day of kindergarden, some birthdays and even some people we meet. It seems that the memory fades with time but why is it that when we're hurt we never forget no matter how old we were. We can remember the blows that gave us our scars for the rest of our days. We dwell, we deal but we never forget and sometime we never get over it. What bandage can you put on an emotional scar what ointment will make it hurt less?
