Thanks for the comment and the addition. "Can't" is another of those words for me too, if I had thought of it.  I just saw a quote by Henry Ford, "Obstacles are those frightful things you see when you take your eyes off your goal."  When someone says they "cannot", I often hear that as "something else is more important to me than our agreed objective."  It definitely needs to be included.  Thanks for catching that. Mike...
