Richards slid the window open, affording Grey a view through the van’s windshield. The sun had set; the road ahead, a two-lane blacktop, was dark and empty. In the distance he glimpsed a purple line of light where the sky met a mountain ridge.

“I need to take a leak,” Grey explained. “Sorry.”

In the passenger compartment behind him, the other men were rousing. Richards reached onto the floor and passed Grey a clear plastic bottle with a wide mouth.

“I gotta pee in this?”

“That’s the idea.”

Richards closed the window without another word. Grey sat back down on the bench and examined the bottle in his hand. He figured it was big enough. But the thought of taking his equipment out in the van, right in front of the other men, like this was no big deal, made all the muscles around his bladder clamp like a slipknot.

“No way I’m using that,” the one named Sam said. His eyes were closed; he was sitting with his hands folded at his lap. His face wore a look of intense concentration. “I’m just holding it.”

They rode a little farther. Grey tried to think of something that could keep his mind off his bursting bladder, but this only made matters worse. It felt like an ocean sloshing around inside him. They hit a pothole and the ocean crashed against the shoreline. He heard himself groan.

“Hey!” he said, banging on the window again. “Hey in there! I’ve got an emergency!”

Richards opened the panel. “What is it now?”

“Listen,” Grey said, and pushed his head through the narrow space. He lowered his voice so the others wouldn’t hear. “I can’t. Seriously. I can’t use the bottle. You’ve got to pull over.”

“Just hold it, for fucksake.”

“I’m serious. I’m begging you. I can’t … I can’t go like this. I have a medical condition.”

Richards sighed with irritation. Their eyes met quickly in the rearview, and Grey wondered if he knew. “Stay where I can see you and no looking around. I fucking mean it.”
