Leo felt a tightness in his chest. His father's silence spoke volumes. They hadn't spoken much, not since… well, not since a long time. The house had always been a neutral ground, a place where they could still, if only for a few hours, be father and son.

Now, that was going. The thought made his throat ache. He wanted to say something, anything. But his tongue felt thick, heavy. He kicked a pebble across the cracked driveway.
