When somebody you've wronged forgives you, you're spared the dull and self-diminishing throb of a guilty conscience. When you forgive somebody who has wronged you, you're spared the dismal corrosion of bitterness and wounded pride. For both parties, forgiveness means the freedom again to be at peace inside their own skins and to be glad in each others' presence.
