The character Meredith Grey narrates this quote played by Ellen Pompeo;
As doctors we can't undo our mistakes, and we rarely forgive ourselves for them. But, it's a hazard of the trade. But, as human beings we can always try to do better. To be better. To right a wrong. Even when it feels irreversible. Of course, I'm sorry doesn't always cut it. Maybe because we use it so many different ways. As a weapon. As an excuse. But, when we are really sorry, when we use it right. When we mean it. When our actions say what words never can. When we get it right "I'm sorry" is perfect. When we get it right, "I'm sorry" is redemption.
