A squiggly story

A young boy wants to write a story just like his big sister. But there's a problem he tells her. Though he knows his letters he doesn't know many words. His sister patiently explains "Every story starts with a single word and every word starts with a single letter. Why don't you start there with a letter?" So the boy tries. He writes a letter. An easy letter. The letter I. And from that one skinny letter the story grows and the little boy discovers that all of us including him have what we need to write our own perfect story.
