Generally when someone forgives another person for a mistake they have suffered, they don’t forget what has happened. They are cautious in case this happens again or they will bring it up when they themselves wrong the other person in order to justify their wrongdoing. To forgive and forget is the highest form of forgiveness; it is as if the mistake has never happened and you never bring it up in a conversation. This is a great ideal to strive for when you forgive someone, but not very easy to achieve.
