That word, Forgiveness; Let's examine its true meaning. It does not mean that we condone what he did. It means that we are no longer willing to let that act simmer in the back of our minds and go on and on about it ad nauseum.(I know that's not a real word, but it should be)
As Omar Khayyam said to the king of Persia, "This too shall pass."
I will never condone what he did and I will never forget it.
