Forgiveness is not like bird poop. You can't just release it and let it fall on the shoulder of somebody who has hurt you, then declare as you swoop off into the sunset, "I have forgiven him! We are now reconciled!"
This was spawned by reading a review of the book How Can I Forgive You? by Janis A. Spring, and by commenting on one of the comments.
