No one writes a story like Lydia Davis. In the years since she began publishing her lyrical, extremely short fiction, she has quietly become one of the most impactful influences on American writers, even if they don't know it. That's largely because she makes economy seem so easy. You could read several of her stories into a friend's voicemail box before you were cut off (and you should). You could fit one of her stories in this column. Some you could write on your palm.
