When you swim far enough away from the shore and, floating on your back, surrender completely to the ocean. Enjoying the sweet sounds and coolth of water lapping playfully at your toes, knees, belly, fingers and cheeks. With your ears submerged just enough in the water that the excited squeals of children on the beach sound like distant memories. And you watch (heart happily sighing) the sweet orange-red and purple flecks of sunlight dance nostalgically across your closed eyelids.
