Write a scene of dialogue in which two friends use allusions to communicate with one another. Their allusions may come from movies, books, or historical events. As you write this allusion-rich dialogue, consider how those allusions affect the reader’s experience. Do they invite the reader in, or do they make the reader feel further outside the experience of the characters. In most cases, inviting the reader into the characters’ relationship is better than excluding the reader. But the most important thing is for you to be aware of the effect you are creating—and that it be the effect you were going for.
