Upon meeting others, most of us are courteous. But, as familiarity increases, we become more comfortable and, all too often, less courteous. In our fast-paced world, we no longer seem to have the time, or worse, the inclination to be considerate of others. All too often, we take for granted those closest to us: We even end up treating strangers more politely than we do those we know. How much saner the world would be if only we treated those we know and love as courteously as we treat a stranger.
