Lucas Knight is a very nice boy who's on a trip to visit his grandmother across the state. After a while on the freeway, he stops at a seedy rest stop to use the bathroom. While peeing, Lucas notices something on the bathroom stall wall, the likes of which he's never before seen. Among various graffiti markings, there's a hole big enough to fit a hand through it. As he walks away, after pulling his pants back up, he hears coughing coming from inside the stall. He pauses. Some writing on the wall indicated that coughing meant someone wanted to engage sexually with whoever else was in the bathroom.
