The email landed in Daniel's inbox like a lead weight. The college, the place where he had spent the best years of his life, was closing. He felt a deep, hollow emptiness in the pit of his stomach.

He immediately called his best friend from college, John. John answered in a shaky voice. They reminisced over the phone, laughing and lamenting at the same time.

Later, Daniel found himself rummaging through a box in his attic. He unearthed a stack of letters, photographs, and old concert tickets. The past had returned, and it felt like being embraced by a ghost. He felt an intense pull toward something he could never get back.
