I can tell by his windows

I can tell by his windows.

He left the bathroom one way open. He never does that if he is leaving the apartment.

His office light is on, I can see it behind the purple curtain.

But his living room is dark.

He moves through his space without lights. Feeling around by instinct, by intuition, where the coffee table is.

Looking out at the world from his cave.

He is alone.
