I remember once walking along the beach with a friend. We spoke intensely about our relationship, trying hard to explain ourselves to each other and to understand each other’s feelings. We were so preoccupied with our mutual struggle that we didn’t notice the magnificent sunset spreading a rich spectrum of colour over the foam-capped waves breaking on the wide, silent beach. Suddenly my friend exclaimed: “Look. look at the sun, look!” He put his arm around my shoulder, and together we gazed at the shimmering ball of fire vanishing gradually below the horizon of the wide ocean. At that moment, we both knew about hope and joy.
