The daughter getting farther away in the Greyhound Is beyond where I can imagine. Interior running lights of phosphor-green Show a faint shape of her head, reflected on the glass, Against the Dakota night. I try to resolve the picture, but the Badland darkness Empties her silhouette. If she had to leave, it should have been in a perfect vehicle, But she rides that dirigible of the road, Dispatched by a breakdown scab corporation Into a triangle my wavelength will not reach. The sealed-off revolutions of engines Are faster propelling souls at night-time Than my sorting of memories Can fix a negative under ruby light. Yet right here I have a template that strained for her form Among a crowd of children at the schoolyard gate.
