What I am for in my stories is something that is quite literal, not even fictional. They are not even stories. What makes them literary, then, is the exact tone that I am trying to strike, which gives the literal detail a metaphorical resonance. The story about the shirts, for example, is a literal account of my own system of wearing shirts. If it doesn't resonate farther than that, it is fine, but then it isn't a particularly good story either. For example, it doesn't have the revelatory nature of Thomas's example from Saul Bellow, of a man drying himself with yesterday's dirty shirt.
I've been thinking of metaphors that are not even metaphors. Like closeness (in physical terms) being emotional closeness, or weight (mass of objects) being metaphorically importance. Maybe resonance is like this too: literally, sounds vibrating, and metaphorically, a story resonating with its reader.
