A story for you

I was sitting in the hallway a ways down from my Philosophy room doing some studying before class. People were consistently walking by, just one or two at a time, going out the doors to my left, up the stairs or into the Philosophy department behind me, or down the hallway to my right, for the first 25 minutes or so that I was there. A few more minutes passed and I realized that quiet had taken over. I looked to my left and to my right and saw no one. Even outside the doors I saw no one in the quad. The thought that entered my head was "You know, I could be naked right now and no one would know about it."
