John whistled as he unpacked his boxes in the guest room. The walls, painted a calming shade of blue, felt instantly comforting. His dad's voice, booming with laughter, drifted up from the living room. "Finally got the band back together!"

He chuckled, picturing his father's face. After weeks of battling loneliness in his tiny apartment, the thought of his parents' company was almost intoxicating. He felt a lightness he hadn't experienced in ages.

He grabbed a photo of him and his dad from his box. It was from a hiking trip the year before. He grinned, feeling a surge of affection. He was looking forward to this, more than he could have ever imagined.
