Michael stared at the invitation, the glossy paper reflecting the harsh fluorescent light of his office. He felt a dull ache behind his eyes. He hadn't thought about high school in years. Then, the reminder.

He walked to the window, gazing out at the city skyline. It was a long way from the quiet suburban streets where he had grown up. He thought of the football games, the pep rallies, the awkward dances. He remembered the feeling of invincibility. It seemed like a lifetime ago.

He picked up his phone and called his sister, Sarah. They spoke of memories, of people, of shared secrets. The conversation warmed him, a reminder of a simpler time and of the people who shaped him. He hung up feeling lighter, less burdened. Maybe he would go.
