Speaking of logical things, at my very first tech writing job, as I set off on this long, winding, and slightly peculiar road, my boss told a story about an engineer who was tired of being interrupted in his very own patch of cube land.
So, he stretched a string across the opening of his cube and hung a sign that said "Logical Door." Nobody bothered him. Now, he was in the engineering department, and thus surrounded by fellow geek soulmates. Someone like me, however, would probably have interrupted him to ask what it meant . . . . OK, back to work. --Nancy
