"No, no, no," Mark whispered, reading the headline again. His hands were trembling. He’d just learned his beloved college was shuttering its doors. It felt unreal, like a bad dream.

He went to his garage and pulled out a box from the attic filled with his college memorabilia. He opened it, breathing in the scent of aged cardboard and forgotten dreams. Inside were old textbooks, a graduation cap, and a tattered flag bearing the school's colors.

He picked up a photo of his group of friends, all smiling, happy, and full of hope. He remembered the feeling of invincibility, the belief that they could conquer the world. He felt a tightness in his chest, a yearning for those days he could never quite recover.
