Magical Security Guards

On Monday morning I went to campus early to ensure that I'd get a certain French assignment completed and turned in by 9 AM. I was sitting in the library with my computer and my books scattered across a desk for a couple of hours, working feverishly. For some reason, when I haven't gotten enough sleep, my allergies kick in, and Monday morning my nose was running like crazy. I had a pocket pack of tissues in my bag, but I quickly used all of them. There weren't but a handful of people (nothing compared to how many there are around noon), so I thought it'd be okay to run to a bathroom quickly to take care of my nose situation - without packing up my stuff of course. I actually jogged to and from - it couldn't have been more than three minutes that I was gone. But upon my return, I noticed a little card that had been placed on my keyboard. I looked around quickly like I was in an espionage movie or something. The only time I've seen security guards is when I'm on the 3rd floor late at night - they'll occasionally walk by the row of study desks with heavy footsteps and stern faces. They must have cameras...or magic!
