For one young boy, it’s a perfect summer day to spend at the beach with his family. He scours the high tide line for treasures, listens to the swizzling sound of barnacles, and practices walking the plank. But mostly he waits for high tide. Then he’ll be able to swim and dive off the log raft his family is building. While he waits, sea birds and other creatures mirror the family’s behaviors: building and hunting, wading and eating. At long last the tide arrives, and human and animal alike savor the water.
