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.
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
