This is a short story about a boy, Jamie. His family is homeschooled and often takes trips to the local playground park for a day off. He's seven with an older teenage sister, Margie (whom he affectionately calls Mar), and a younger brother, Paul. His mother keeps watch over them, but Paul keeps her undivided attention any way he can. Mar doesn't give two spits about the world and often closes off. It is because of this negligence that Jamie is kidnapped.
