time's up

Let's face it. Sometimes classes are boring and one finds themself staring at the clock more than anything else. This is never a wise thing to do, as it makes the class appear to drag on for eternity, but it seems to be an inevitable, habitual act. No one is persistently immune to this activity. If they are, they should probably write a how-to book. It's not very encouraging to check the time only to discover that a mere 3 minutes has passed since the previous compulsive glance at the clock.
I myself often suffer from restlessness during my many boring and tiresome classes. I attempt to peek nonchalantly at my watch or take a quick gander toward the clock when the professor isn't looking. I try to be sneaky like that, so as to not give them the impression that I find their lecture any less than interesting. However, sneakiness was unnecessary yesterday during my Women in the Visual Arts course.
My painfully computer illiterate professor had been projecting the computer screen onto the wall, so that we could view some pictures on a website, using the fancy-dancy technology that she doesn't quite know how to use. Later, as she stood in front of the class speaking of nothing, the computer desktop could still be seen behind her.
At this point, my attention span had expired. I stared into nothingness as my leg began to shake and the urge to check the time arised. I looked up at the professor for some indication of whether or not she would soon be ending her useless rambling. She stepped to the left and the computer's time displayed right across her forehead. (I know there is a good word for this and how representational it was, with this being all that was on my, and many others', mind. It's killing me, but I just can't think of it.)
I'm afraid this only increased my awareness that time was moving slowly and that I couldn't wait to get out of there. On the bright side, I must have looked extremely attentive during those last five minutes.
