Re: Well if the US ships want the Chinese to keep out of the way
The worst single day I've ever had with teaching computer (I was the only computer-literate in the place) to a secretary. She had thoroughly absorbed the lesson of the typewriter: hit return at the end of the line. No amount of demonstrating, explaining, pleading, or exhorting did any good. I gave up in despair, and went away.
An hour or two later, I was called before the Director. I had made that secretary cry. I was later told by the other people in the office that she'd asked me because she was afraid to ask the director.
