Liam stared at the ceiling, the dim light of his bedroom doing little to penetrate the bleakness. He hadn't touched his guitar in days. The music had gone silent inside of him. The online friendship with “IndigoDreamer” had been a lifeline, a shared solace in the face of his solitude. They had discussed everything from favourite bands to his fear of the future.

He’d described his neighbourhood a hundred times. Now, a delivery driver rang his doorbell. Picking up the pizza, he glanced at the receipt. The name was one he recognised. He turned back, the pizza box sliding from his numb grip. A figure was standing across the street, waving. It was her, a cascade of dark hair, a familiar face, a shy, hopeful smile.
