One day you'll wake up, the sun will be bifurcated by the Venetian blinds, and it will be in your eyes.
You'll blindly reach across the bed and touch only faintly-warm sheets. The expectation of skin, of kin, of the person who helped build you a family.
After all these years how could he leave? No, you're just being silly. He's just up early, making coffee. You'll pry open your eyes and gaze into the hall, scanning for movement.
Scanning for anything at all.
Low beams of morning sun cut through the room, and the only things moving are gently wafting motes caught in it's brilliant web.
You'll want to call out, maybe make a silly joke. Ask him if he's making breakfast, ask him if he broke the yolk, but instead you say nothing because at least with the silence you can still cope and the sound of your loving call falling flat on the hall walls will be enough to drive you mad.
A car drives off in the distance. The sound is clear as day. Clear as day. Clear as the slatted sunlight strewn across your face. Clear as the last time. Clear as the first time. Clear as it ever could be. A window to forever see through, a door just for you.
