Find interesting and believable ways to drop exposition
Have you ever seen one character tell another, “He’s at Dollar-Mart, you know, that big national chain store?” If it were so big and national, the other character would already know this information! One of the best ways to drop exposition is in an argument. You can then exaggerate and bring out information a character might already be expected to know by using it as a weapon. And for simple exposition, try billboards, newspapers, answering machines, photos on mantles, two people talking about a third, and any other technique that doesn’t hit the audience over the head or smack of cliché.
