Get attention: Paul Jennings' stories are often conversational, like they are being told directly to you by the narrator, and so he uses all sorts of conversational phrases and exclamations. 'All right' is something you might say to get your listener's attention. What else might you say?
Introducing the topic: give a teaser as to what the story is going to be about.
Hype it: tell the reader why they’re going to want to hear about it. Is it a secret? Is it the best story ever? You’re a salesperson after all!
Choose your medium: stories can be told through many ways. It might be direct narration, or through a medium such as a book or letter that they’ve written, or in this case a tape recording.
