Every summer, Dawn Nolting buys her 12-year-old son Isaac a pool pass, and drops him off to swim with his friends. In June, Isaac was hanging out, when he met a friend-of-a-friend, 13-year-old Dakotah Zimmer. The kids at the pool in Washington, Mo., noticed that Isaac and Dakotah looked an awful lot alike -- they have the same hands, the same feet, the same nose, the same haircut --- they even walk alike. Someone asked if they were brothers. Dakotah said he had a brother he had never met who was adopted by a woman named Dawn. "That's my mom's name," Isaac said.
