There are times we are worried about what we or someone else has done, and we wonder, if we or they can go on. There are times
things happen that certainly change our lives and someone else's, and we are forced to go on in spite of what happened.
If the pain of the past rests on your shoulders, day after day, it will get heavy. You have to know how to carry it or how to let it go. You either carry it with forgiveness and understanding or let it go with the same. You may have another choice but you will never have a better option.
Just a reach out of "Forgive me" or "I was wrong" can be very healing to another heart. Sometimes that heart will share further things that you may even love or benefit from hearing.
