When I do a presentation sans presentation aids (as is occasionally my wont), just me and a spectacle of public gesticulation, I see younger people in the audience panic. Are there slides!? No.
They also, as a generalization, scribble and type away like demons from Hell's stenography pool, trying to snatch every word, as though they might miss a word of such crucial importance that their entire comprehension of the presentation be sundered. And sometimes I talk like that, using the big words and ventures into meandering periphrasis and off-piste anecdote, just to make them write more. O sweet, corrupting power!
In other news I cross my 7s too (which seems to perplex Americans more than most), put hooks atop my a's and all my rs are Rs, though I small cap the lower case.
