It's so hard sometimes not to be angry to those harms enforced by others... The point is not to think of revenge, it's to stay focused on your own peace and seize of others. Forgiveness is not something we should do for others, every man should forgive himself his own mistakes. Our mission here, I believe, is not to grudge too much so if a man comes to us with his own forgiveness apologizing for the harm he made to us, we should accept that apologize, but not before! In other words... I would forgive when you realize that you made a mistake cause only that way it would have sense...
