“ The "general public" so sadly abused in book and speech, is quick to recognize courtesy and eager to respond to it. Before a pleasant face and a courteous manner, all obstacles vanish, and we find ourselves progressing easily through the world, making friends as we go. Some of us vainly pride ourselves upon being frank and candid in our association with others. This is a serious blunder which many men and women make. It is not commendable to be frank, when courtesy is sacrificed. ”
