Friendship is held to be the severest test of character. It is easy, we think, to be loyal to a family and clan, whose blood is in your own veins. Love between a man and a woman is founded on the mating instinct and is not free from desire and self-seeking. But to have a friend and to be true under any and all trials is the mark of a man!
