The smell of rich, dark coffee filled the air as David arranged his model train set in the living room. Sunlight danced on the polished tracks, reflecting the meticulous detail he’d poured into each tiny building and landscape feature. His collection had always been a source of quiet contentment. Now, his son, Ben, was consuming everything about the hobby.

Ben practically leaped into the room, his voice brimming with excited energy. “Dad! Did you see the new engine on eBay? Can we get it?” He bounced on his heels, his eyes shining with a fervor that mirrored David's own past passion.

David couldn't help but feel a warmth blossom in his chest. "Let's see, champ. Maybe if you finish cleaning your room." He winked, a feeling of bright expectancy washing over him.
