You cannot judge the quality of another's friendship by superficial appearances, especially when things are going smoothly. It is only when we have experienced the worst, most crushing of times--when we have plumbed the depths of life--that we can experience the joys of genuine friendship. Only a man of principle, a woman of resolve--a person who stays true to their chosen path--can be a trusted and true friend, and have real friends in turn.
