There is a big difference between what we call **reframing** a person’s actions and excusing those actions. For example, if you see that he was under pressure and displaced his anger onto you, you can forgive while at the same time acknowledging that he should not have treated you this way. An excuse is to say that displacing anger is ok, acceptable, or not morally wrong. When you forgive and start to reframe whom the other person is, try to keep in mind that the behavior still is not fair. Your separating a person and his actions may help you to avoid excusing the actions as you forgive the person.
