To love means loving the unlovable. To forgive means pardoning the unpardonable. Faith means believing the unbelievable. Hope means hoping when everything seems hopeless. - G.K. Chesterton
Success is the one unpardonable sin against one's fellows. - Ambrose Bierce
Children are guilty of unpardonable rudeness when they spit in the face of a companion; neither are they excusable who spit from windows or on walls or furniture.
