It's a story because it tells about something, but it's a pretty silly one. All good stories have a beginning, a middle and an end. Some stories even end up in the same place they started. During the course of the story, Tom travels all over the place and has all kinds of adventures, and ends up back at home. So, before you begin to write, sit and think for a little while about the beginning, middle and end of your story.
Every story starts with a main character.
It can be an animal, a person, or a thing. It can be anything you want. If you want to illustrate your story, choose a main character you like to draw. When you start getting answers, draw a character web. Put your main character's name in the circle in the middle, and all of his or her characteristics on the lines coming out of the circle.
