Well, I have survived the rough day. As it turned out, the video watching that I had to do happened with three other guards, two of which were smarter than the tapes and the third didn't speak english very well. Whenever the boos left the room, we made rather snarky comments about what they were showing us, which made thingts not only bearable but also somewhat enjoyable.
I managed to get home by 2, and got some sleep, but my body decided I only needed so much, and I kept waking up. Now I'm back at work, and I know I'll be tired by the end of this shift, bt I'm certainly going to make it through ok. And I get the next two days off, so that'll be good.
