This morning, I was taking over for the Science Skills Lab, off in another building in the process of being renovated. (It was actually where I had my AP classes way back in the day.) Anyway, as I was starting, the person I was taking over for called to warn me that the police were doing some training and might be firing off guns. Let's just say that it was a good thing that I was told, because I did hear gun shots. I think they came from outside, but guns are not the type of thing you want to hear at work.
