The discovery left Mark giddy with an inexplicable joy. He’d been renovating the old house, stripping back the wallboards, when his hammer hit something solid. A small metal box. He didn't recognize it, but a potent, buzzing anticipation filled him.

He wrenched it open. Inside were a packet of baseball cards, a comic book and a letter. He couldn't quite contain the sheer thrill of it all. The world was suddenly vibrant, alive. His legs bounced with a restless energy as he began to read the letter.

Mark felt the world tilt a little. He began laughing. The sound was free and easy, like a bird taking flight. He raced outside, throwing his arms wide, relishing the moment.
