Once, you have decided on a set of well-formed embedded commands, what you need next is a story. It can be any story around any theme. The story acts as a vehicle to deliver the embedded commands. It feels natural and is easier to say a story that is relevant to the context and also the interest of your listener. So, it can be any story. The important thing is that you keep your listener engaged with your story. And all you got to do next is embed the suggestions within the story. The simpler and shorter your suggestions are, the easier to embed them.
