The phrase “we (I) (you) simply must -” designates something that need not be done. “That goes without saying” is a red warning. “Of course” means you had best check it yourself. These small-change clichés and others like them when read correctly, are reliable channel markers.

The appropriateness of Heinlein’s wisdom is probably endless.–Joe]
