He leaned back in his chair, the letter clutched in his hand. It was a letter he'd written to his dog, Max, years ago, but never delivered. The dog had passed a long time ago. He’d found the letter in a box of old pictures.

He pictured the dog's tail wagging. The letter was filled with simple joys. He recalled the warmth of a furry body pressed against his leg, the comfort of knowing that someone was happy to see you. His chest tightened.

He closed his eyes, the image of his loyal companion vivid in his mind. The room became filled with an echo of a time that was gone forever. It felt like an ache in his soul.
