Friendship is an experience everyone enjoys to some degree. The memory of a friendship includes gratitude for moments shared, feelings understood, anxieties lifted. And a feeling of self-worth is involved, knowing that something of oneself was given and found valuable by a friend. Readings and poems by such noted writers as Ralph Waldo Emerson help readers examine friendship from many perspectives. Friendship is seen as a fresh wind on the spirit, a glory in life. C. S. Lewis writes that friendship is a necessity, not in order to live, but to make living worthwhile.
