A mistake is always forgivable, rarely excusable and always unacceptable.
Always forgive your enemies - nothing annoys them so much.
Forgive many things in others; nothing in yourself.
Forgive your enemies, but never forget their names.
Forgiveness is a funny thing. It warms the heart and cools the sting.
Forgiveness is the economy of the heart... forgiveness saves the expense of anger, the cost of hatred, the waste of spirits.
