Heโ€™d been wandering through the park, head down, replaying a rejection letter. Suddenly, a melody snagged his attention. Mark stopped, rooted to the spot. It was his song, "City Lights." He knew the opening guitar riff anywhere.

He felt a buoyancy, an unexpected lightness in his limbs. A tingling sensation travelled from his toes to the top of his head. He looked around wildly, his eyes scanning the park. There, under the old oak tree, a group of buskers were playing.

Mark stumbled towards them, a wide smile breaking across his face. He wanted to shout, to applaud, to do anything. He just stood there, lost in a swirling, beautiful sensation, absorbing the music. He felt an intense urge to share the moment with someone, anyone. He pulled out his phone, searching for his best friendโ€™s contact.
