Forgiveness

It's so hard to forgive someone that's done something so harsh to you. It's especially hard when they don't think they've done anything to hurt you. God calls us to forgive others because he has forgiven us. He died on the cross for OUR sins so that we could have eternal life. The question is, what if someone has done something to you that has deeply hurt you but they don't realize it. Do you still go to that person and tell them you forgive them when they don't even think they've done anything wrong?
