OK, let’s dispense with the obvious—namely, that there is a kernel of truth to the old saw “Show, don’t tell.” Fiction is a dramatic art, and you need to dramatize, not simply state things. The sentence “John was a handsome man” is not a handsome sentence, and though a writer is welcome to use it, she shouldn’t think it will do much work for her. Similarly, in the first workshop I ever took as a student of writing, when someone wrote “An incredible feeling of happiness washed over her,” the teacher said, “First of all, get rid of the ‘washed over’ cliché, and second of all, if in the course of an entire novel you can evoke an incredible feeling of happiness, then that’s a major accomplishment.”
But it doesn’t follow from this that a writer should never say a character is handsome or happy. It doesn’t follow that all a writer should do is show. To my mind, the phrase “Show, don’t tell” is a wink and a nod, an implicit compact between a lazy teacher and a lazy student when the writer needs to dig deeper to figure out what isn’t working in his story.
