Given the question: I showed up at the address on Columbine's invitation just before eleven; it was a converted warehouse in an industrial zone on the city's north side. Since it was a Saturday night, everything else was empty for miles. The parking lot was filled with sports cars, hybrids, and shiny suburban tanks. The door facing the parking lot was open, spilling out muted lights and the din of yuppie chatter. It cast a somewhat foreboding aura over the entrance. The first thing I noticed as I approached was the beefy refrigerator in a rented tux blocking the doorway. The second thing was the surveillance camera perched on the wall above his head. I had stopped home and changed first, so I was sure I was dressed mostly appropriately for some rich faux-hipster art party - charcoal gray pinstripe jacket over a TV on the Radio t-shirt, skinny cuffed jeans, Docs, and a black fedora. I certainly didn't look any worse than the other idiots I saw filing in and out of the door. I even had an invitation. So I was fairly confident I'd be able to gain admission to this thing without incident. "No, absolutely not," the doorman said, pressing a meaty palm into my chest. "I was invited!" I said, exasperated. "I have documentation." I waved the rave card in front of his face. "No dice." I stepped aside to let a couple of aging goths through the door and wondered for a moment if the doorman somehow knew who I was. Then I noticed the ear piece he was wearing and my eyes darted back to the surveillance camera. "Motherfucker," I spat and raised both arms to flip off the camera. I didn't know it at the time, but at that moment Dylan Maxwell was sitting in front of a wall of monitors, laughing his ass off. Question: When did the narrator notice the man in the doorway?
