For there are two kinds of forgiveness in the world: the one you practice because everything really is all right, and what went before is mended. The other kind of forgiveness you practice because someone needs desperately to be forgiven, or because you need just as badly to forgive them, for a heart can grab hold of old wounds and go sour as milk over them.
