Konrad, you could say whatever you wanted to for 90 minutes and he wouldn't do a thing; for Wurtz, the minute you questioned anything, even politely, it was a caution. Which of these officials, in your estimation, had fewer instances of dissent across their career?
It is about finding what you are comfortable putting up with and drawing the line there, firmly and consistently.
