First off, let me state that I am NOT joking. This is 100% real, but I hope I'm just being really paranoid. About a half hour ago, a man came into the computer lab I'm monitering. He didn't look like a student or a teacher. He looked kinda like a homeless guy, or a guy who isn't very clean. Anyway, he came up to me and asked what the lab hours are. I told him we close at 5:00pm. He pulled up a seat and started talking to me about a wireless internet thing that I knew nothing about. I nodded when he said things like Routers and USB ports... but the rest was gobbledegook. Anyway, it seemed to me that he was trying to sell me something. I told him I wasn't interested and he just kept talking about how great it is. I finally said that I didn't need it, but my cousin might be interested (Things like this are right up his alley). I asked if he had a card, and he nodded. He unzips his huge, bulging backpack and starts digging through it. He pulls out a ceramic statue of a Yak. After making a joke about the Yak's visible genitals, he sets it down and starts digging through various folders. I notice he has about 5 different binders full of papers, and he pulls out a couple of drawings, lets just say they are in the genre of satanic erotica, or at least fantasy erotica. Finally he pulls out a peice of paper. Then he digs through his dirty ski jacket for a pen. He reaches into an inside pocket and produces three Snickers candy bars and puts them on my desk. After some more searching, I ask if he needs a pen, and hand him one off my desk. He writes down a scribled name, his e-mail address, and a telephone number. He asks me to write my number on another piece of paper, but I tell him the best way to reach me is through my e-mail. I was writing down my e-mail when I realized I might not want this guy to have it, so I wrote down yahoo.com instead. He gathers his stuff up and asks me to talk to my cousin about the stuff he wants to sell for $400 or $20 (He said both, I have no idea what he was talking about). Then he's leaving, and I give a sigh of relief. As he gets to the door, he notices the Lost & Found and starts digging around through it. It doesn't look like he took anything, but he comes back and says he'll be back before 5:00pm and asked if I could give him a CD-RW. I told him we don't sell them in labs anymore. He nods and says "see ya later." Okay, you are probably thinking, "So what? Why did you say you feared for your safety?" I'm not sure, but I got a gut feeling this guy was trouble. I hope he doesn't come back at the end of my shift, but if he does, I have no idea what will transpire. I guess he didn't do anything illegal but I'm just freaked. Am I totally paranoid or what?
