Deliver a message to your readers in your own passage.
Step 1: Decide on a Theme
Step 2: Imagine a situation that will allow you to convey your theme.
Step 3: Think of some details that will strengthen the effect of your theme.
Ex: Suzie is trying to convey the idea that texting while driving is dangerous and wrong (step 1). She has decided to write about a pedestrian getting run over by a driver who is texting (step 2). Now think about step 3. Does it matter who gets run over? If an evil criminal gets run over, does it have the same effect as an elderly lady? A mother with a stroller? Imagine a teenager who has just opened a letter that says he’s getting a full scholarship to Harvard. Now a bright future has been snuffed out. In the story, the first person to respond on the scene of the accident will find the driver’s cell phone on the ground with half a text message on the screen (more interesting than a narrator saying the driver was texting). Does it matter what the text says? If the driver was sending an urgent text to a dying loved one while she was rushing to the hospital to see this person one last time, is the theme reinforced as effectively? Now imagine the text contains unimportant gossip. Does the reader feel more strongly that the driver shouldn’t have been texting? If the gossip contains negative information and the driver is being mean to someone, does it strengthen this feeling?
