He found it, the picture of him and Kevin Riley, in matching soccer jerseys, grinning crookedly at the camera. He remembered the sting of Kevin's taunts, the shove in the playground. Now, Kevin Riley's name was on a sign, a therapist. He had a practice.

He sighed, the air catching in his throat. He felt a deep ache, a yearning to revisit a past he knew he could never fully reclaim.
