Did you hear the one about the brilliant-but-eccentric system administrator who didn't know how to manipulate data in a spreadsheet? Its because he was a brilliant-but-eccentric system administrator.
"How can you not know Excel?"
"How can you not know what I do for a living?"
Its like I asked the Project Manager who had requested the spreadsheet. "When was the last time I asked you to log into a unix box and fix a filesystem for me?"
Being in imagery intelligence (versus, let's say signals or emissions intelligence) was equally as problematic. Your average visiting dignitary never wanted to second-guess your interpretation by "reviewing" your wavelength. Whatever. But if you had pictures? Well then EVERYONE was a photographic expert!
Heh - "reviewing your wavelength." God I crack myself up sometimes.
