Code words do not work that way!
While I was on my medically enforced sabbatical from Purgatory, a system was developed so that those who are facing the door and can see what is coming could warn those who's cubicles face the wall (like mine does) that one of the Chinns was coming in. A simple declaration of "Man Down" is all the warning needed.
The thing is, this code has become the catch-all for EVERYTHING, whether the Chinns are in or out or in between. Cell phone rings because you forgot to turn your ringer off? "Man Down". Coffee pot is empty? "Man Down". Out of Cheez-its and needing a nosh? "Man Down".
It is (or at least it SHOULD be) a universally accepted fact that code words cannot have too many meanings, or else you have to define which meaning the code word is being used for, and this negates the effectiveness of code words.
Bunch of monkeys on the ceiling, sir! Grab your egg-and-fours and let's get the bacon delivered!
Why is it still Thursday?
