This is actually crazy. The walls have ears. That phrase goes back to the Middle Ages. Just to give you a clue, back in 1978, I was on a evening shift in the Tech Control Facility and had a monitor speaker on one of the Autovon lines back to the States. I happened to hear a call which turned out to be my Squadron Commander talking to a friend. He was bad mouthing his executive officer saying he was a clueless dork.
Anything anyone can do is just pabulum to lull you into complacency.
