The setting sun cast long shadows across the living room, painting the space in hues of orange and purple, yet giving no warmth. Robert sat in his armchair, the evening news playing on the television, unheard. His son, Max, had become a solitary figure, retreating into his room, shutting the door behind him.

He’d found the account, a carefully constructed façade, a world he'd been denied access to. The profile was of Max, but a Max who seemed unhappy, a Max who seemed almost... angry. The world behind the screen felt like a world without him.

Robert felt a wave of sadness wash over him. He felt as though he'd lost something, he wasn't sure what. He felt a profound sense of loss, a gnawing emptiness, a quiet ache that resonated deep within his bones.
