A few years ago, the National Archives published the manual that my former self would have been taught during her initial training course. As you can probably guess, I've since purchased it. I read through the Security Talk, and I got... for want of a better phrase, the chills. The whole book, a little smaller than an A5 notebook, gives me the chills. As I read it, my mind seems to draw back to the time my former self was taught its contents. It's making it difficult to read it right now.
