Thanks for the re-direct Tom.
Boudreax,
I try to "avoid absolutes" when I am teaching, or even making TV, because the exceptions undermine the legitimacy of the point you are trying to make. While I would agree with the premise that "you can't count on hitting your target in the expected spot when you shoot through glass," to categorically say that "you can't hit with the first shot" is to paint with too broad a brush.
