Forgiveness is so interesting that we could forgive even our enemies even someone that hurt us badly. Your mom was able to forgive your dad because she knows the benefits of forgiveness and she wanted to free her mind from burdens. I believe your mom was happy after she had forgiven your dad right that's one advantage of forgiveness, it light up smile on our faces. forgiveness is a smiling pill because it forces us to smile no matter what it take.
