“You go,” Daddy said simply. His knuckles were like old rope, but his grip was sure. “Take the roads that scare you. Call when you can. Don’t forget how to whistle.”
P2 had arrived that morning with a packed bag and a plan that had changed three times. V10—the quiet engineer from the floor above—had helped him lift the suitcase up the stairs without a single word, hands steady, eyes careful. They had both grown used to carrying things for Daddy: parcels of groceries, heater parts, the small kindnesses that went unnoticed until tonight.
Inside, Daddy moved slower than memory allowed. He set a kettle on the stove, the same one with a chip on its rim, and hummed along to a song on the radio. The melody snagged on P2’s chest when the door opened and he stepped in, rain beading on his jacket.
Outside, the rain slowed to a hush. Streetlamps flickered into life and the city smelled of wet stone and possibility. P2 zipped his jacket and shouldered the bag. He paused in the doorway; the three of them stood like a small constellation, familiar and true.
