Looks like the unreasoned fear of the technically inept.  And I do mean visceral <i>fear</i>, like a sense of imminent danger.<p>I remember once in &quot;technology&quot; class where we were asked to compose a small document with Corel WordPerfect, with a clip art.  Well, I mistook &quot;graph&quot; for clip art, and got a weird square where I should have had a pretty icon.  And I didn&#x27;t know how to remove the square (couldn&#x27;t select it with the mouse, and I didn&#x27;t think of trying backspace or undo at that time).  So I asked for help.<p>The <i>instant</i> the teacher saw my document, she said &quot;Ahh, he crashed my computer!&quot;, then promptly closed the document without saving it.  (15 minutes of work, dammit!)<p>Simply put, she didn&#x27;t have the slightest idea about what went wrong, and assumed the worst.  I flipped the bozo bit at that point, and never trusted her again.
