I don’t consciously avoid metaphors, or similes for that matter. If they don’t happen in my writing, it may be because I find the thing I am writing about compelling enough without comparing it to something else. Maybe I don’t want to introduce some completely different world or image. For instance, in the case of the cornmeal making little drops of condensation in the story “Cornmeal,” I could say, “like little nipples on the underside of the plate,” but then you introduce nipples into the story. Or dew drops—“like little dew drops”—but then you introduce the outdoor landscape. If I avoid metaphor, and if I have to think of a reason why, it may be that I don’t want to distract from the one thing that I’m concentrating on, and a metaphor immediately does that. It introduces some completely, even incongruous, other image and world. And it can work very beautifully, but maybe I don’t want to leave the scene of what I’m describing.
