Fact: Good stories always include irony.
There are many examples of this. For example, in Jurassic Park 3 (Not a good movie) when Alan Grant finally gets a hold of a phone and calls the states, the little boy that answers it is too busy watching Barney to really help them. Barney is a dinosaur. They are about to be eaten by dinosaurs. That's irony.
People are drawn to irony because they sense that they actually spend most of their lives doing something ironic themselves. Reading books with irony, when one oneself is struggling with irony is ironic. Irony gives stories a sense of realism. It also allows people to scream "Oh the irony!" Which is ironic
THE CHALLENGE!: In 300 words or less, write about an occurrence during your day. Then make this scene as ironic as possible.
