That is not to say a certain civility isn't in order. The gentleman will read this sort of thing, nod sadly, smile, and wait until the author is no longer in sight to crumple it and use it as kindling for the wood stove. And there is a certain crossover to be cultivated as well: negotiating skills, for example, especially when they're enhanced by pressing the muzzle of a .357 magnum into the other fellow's forehead. There's plenty of room for nice so long as nasty remains in reach. Welcome to manhood.
Living according to the Mattis Doctrine suits me:
Be polite, be professional, but have a plan to kill everybody you meet.
