"Excuse me, I need to use the restroom." Mark mumbled to his dinner guests, barely able to keep his face serious. He fled from the dining room, his heart racing. He’d recognized the opening bars. His song. Playing from the restaurant's background music.

He practically skipped down the hallway, the sound of his tune growing clearer with each step. He reached the entrance of the kitchen and peeked around the corner. The kitchen staff was moving with their own rhythm, and he saw one of the cooks humming along to the melody. He felt his cheeks flush, his chest fill with air. He couldn't help it. He clapped his hands in a burst of enthusiasm, which startled a line cook.
