Vice President Dick Cheney was caught on camera sleeping during a briefing on the California fire situations. My first thought was what is that guys problem? When he's not blowing up countries or shooting friends in the face, he's sleeping on the job.
But the longer I thought about it, the more I realized well I've did that too. A few years back, on a rather slow day at the library, I began nodding off at the reference desk. I tried to fight it with a friendly game of FreeCell, but alas, I could only fight it for so long, and I fell asleep at the desk. I slept for over a half hour; when I finally woke up, I realized not a single person had even noticed I was asleep.
