Over the nightclub music He will yell “HI!”
She’ll laugh at his awkwardness and then they’ll talk, dance, exchange numbers. He’ll see her for dinner, where they’ll make in-jokes; finishing off each other off in his apartment. She’ll teach him how to cook and he’ll show her his sketches, and together they’ll rescue a kitten. Till sick of sharing it, all three move in together, watching cartoons till the mornings.
They’ll get married with sand between their bare toes, somewhere far away from this club.
As none of that happened except in his head, so he finished his drink and left.
