Lord, make me an instrument of your peace; where there is hatred, let me sow love; where there is injury, pardon; where there is doubt, faith; where there is despair, hope; where there is darkness, light; and where there is sadness, joy
I can forgive, but I cannot forget, is only another way of saying, I will not forgive. Forgiveness ought to be like a cancelled note - torn in two, and burned up, so that it never can be shown against one.
