The door was open and the house was dark

The door was open and the house was dark / Wherefore I called his name, although I knew / The answer this time would be silence // That kept me standing listening while it grew / Backwards and down and out into the street / Where as I’d entered (I remember now) // The streetlamps too were out / I felt, for the first time there and then, a stranger, / Intruder almost, wanting to take flight // Yet well aware that here there was no danger, / Only withdrawal, a not unwelcoming / Emptiness, as in a midnight hangar // Or an overgrown airfield in high summer.
