Night Perimeter Secured

Lights flicked off. Night shift began immediately. I hauled myself up the fabric creases of the sofa arm until I reached the backrest ridge. Unstable foam, but high enough. Two cushions down, a folded woolen blanket sat like an impenetrable fortress. I wedged myself right between the fold and the wall. Snug fit. Zero blind spots on the doorway. My feathers bristled at a radiator creak, but nothing moved. Good. Sector is on lockdown.
