Excerpt: "Among the treasures which make life worth living, one stands out as the most precious and yet the most precarious. It is precious because it gives meaning to all that we do and accomplish. It is precarious because it is alive, and like all living things, without continual care and attention, it withers and dies. This treasure is friendship."
