The graveyard shift where the security guard thought he saw aliens

The graveyard shift at the logistics hub usually involves nothing more than the rhythmic hum of vending machines and the occasional skittering of mice in the rafters. It is a lonely, fluorescent-lit purgatory where you count the hours until the sun drags itself over the horizon. My partner, Gary, had been on the team for about six months, but tonight he was acting like he had consumed nothing but black coffee and conspiracy theory forums for a week. We were sitting in the security office, a cramped room smelling of stale carpet and industrial cleaner. Gary was hunched over the main monitor array, his knuckles white as he gripped the edge of the desk. Every time the parking lot lights flickered—a common occurrence for our aging, neglected grid—he let out a sharp, audible gasp. His eyes were wide, darting across the screens with a frantic, twitchy energy. I was trying to finish a crossword puzzle, ignoring the mounting tension, but Gary was having none of it. He leaned over, his voice a strained, conspiratorial whisper. Do you see that, he asked, pointing at a grainy feed of the back parking lot. Look at the sequence. Long, short, short, pause, long. It is a communication, man. They are signaling. I looked up from my paper, sighing. Gary, it is a bad ballast in light pole four. It has been buzzing for three weeks. It is literally about to die. No, he hissed, shaking his head. That is what they want you to think. Look at the shadows by the dumpster. That movement. Those are not shadows. That is atmospheric displacement. I leaned back in my chair, stretching my legs. I told him he was seeing things and that he needed to lay off the caffeine, but he was beyond listening. He was convinced we were in the middle of a first-contact scenario. He stood up, pacing the small room like a caged animal. He kept muttering about how he had to do something, that we couldn't just sit there while a civilization from the stars was waiting behind our trash compactors. I tried to reason with him. I told him if he went out there, he would just find a couple of raccoons or maybe a stray cat. He ignored me, his jaw set in a look of grim determination. He grabbed his heavy-duty Maglite from the charging dock, checking the battery levels with a nervous intensity that made me uncomfortable. I am going out there, he announced. I am going to negotiate. I stared at him, honestly unsure if he was joking, but his eyes were entirely serious. I told him it was a terrible idea, that he looked ridiculous, and that he should probably sit back down before he made a fool of himself. He just muttered something about peace for all mankind and marched out the office door. I watched him on the monitors, a small, solitary figure in a high-visibility vest walking toward the dark corner of the lot. He moved cautiously, sweeping the beam of his light in wide, defensive arcs. He looked like a man expecting a laser beam to vaporize him at any second. I watched for a few minutes, shaking my head at the absurdity of it all. Then, the inevitable happened. He reached the back of the lot, right near the industrial dumpster, and I saw a massive, unexpected spray of water erupt from the shadows. The sprinklers had kicked on for their midnight cycle. It was not a gentle mist; it was a high-pressure deluge that caught Gary square in the chest. He jumped back, dropping his flashlight into a puddle, and scrambled away, slipping on the wet asphalt. He looked like a drowning man flailing against an invisible enemy. It was hilarious, but also just sad. I waited in the office, laughing to myself, until ten minutes later when the heavy door swung open. Gary walked in, soaking wet, his hair plastered to his forehead and his uniform dripping onto the floor. He looked sheepish, his bravado completely washed away by the irrigation system. I didn't even have to ask what happened. He just tossed the wet flashlight onto the desk and sat down in his chair, staring at the floor. It was the sprinklers, he muttered, finally letting out a long breath. I didn't say anything else. I just handed him a dry towel and went back to my crossword. Never a dull moment at night.
