Poem about killing birds

Torque

After his ham & cheese in the drape factory cafeteria,
having slipped by the bald shipping foreman
to ride a rattling elevator to the attic
where doves flicker into the massive eaves
and where piled boxes of out-of-style
cotton and lace won’t ever be
decorating anyone’s sun parlor windows.
Having dozed off in that hideout he fixed
between five four-by-six cardboard storage cartons
