In my long ago youth, I had a job as a stenographer, taking things down in shorthand and transcribing them. I sure as hell knew precisely what they meant.
BTW, from what I've read, I do not believe that just any random person was assigned to any job for the commandant of a prison camp -- only people who were steadfast supporters and could be counted on to be loyal to the cause. As to her tender age, some of the cruelest women guards were of similar age. I'm not saying this was true of her, but age didn't seem to make much difference. Many of the most rabid Nazis were people who had come up through the Hitler Youth groups.
