“The best way to get along is never to forgive an enemy or forget a friend.”
“Forgive your enemies, but never forget their names.”
“To forgive is not to forget. The merit lies in loving in spite of the vivid knowledge that one that must be loved is not a friend. There is not merit in loving an enemy when you forget him for a friend. ”
“It is easier to forgive an enemy than to forgive a friend.”
“It's all very well to tell us to forgive our enemies; our enemies can never hurt us very much. But oh, what about forgiving our friends?”
