He had woken up with a song in his heart. Mark, usually a stoic presence, felt an irrepressible energy coursing through him. He whistled as he organized his desk, a task he usually dreaded. Then, hidden inside a file, he discovered a letter. It was written to his best friend, a letter he'd forgotten.

His shoulders shook with silent laughter as he read the words. The memory of his younger self brought a smile to his face, and a feeling of exhilaration. He felt the need to share this, to connect with the past. He felt like a balloon, ready to take flight.

He ran to his phone and immediately dialled his old friend’s number, his voice bubbling with uncontainable joy. He needed to recount the story, to share the rediscovery.
