The hum of the server room, usually a background noise, felt like a pressure against Arthur's eardrums. He sat slumped in his chair, the glow of the monitor reflecting in his vacant eyes. He’d skipped the team meeting, claiming a migraine.

He hadn't been to see his family for weeks. He found himself wishing he could simply vanish. The thought of speaking, of interacting, felt impossible.

“Did you ever do the ropes course at summer camp?” asked Beth, startling him.

Arthur jumped slightly, his hand flying up to his chest. He hated being surprised.

“Ropes course?” he croaked. He paused. He was usually much better at making conversation.

“Yeah, Camp Timberline. Tough, right?” Beth said.

A flash of something, a sharp pang, cut through his ennui. Arthur felt a sudden constriction in his chest.
