Anger is a killing thing: it kills the man who angers for each rage leaves him less than he had been before - it takes something from him.
Heaven has no rage like love to hatred turned nor hell a fury like a woman scorned.
How does one know if she has forgiven? You tend to feel sorrow over the circumstance instead of rage you tend to feel sorry for the person rather than angry with him. You tend to have nothing left to say about it all.
