This is my pet peeve with reading...when I am expected to know things that I cannot possibly know in order to make sense of the piece. Such as "You know how Bill does that thing". How the heck do I know Bill? What thing? Sometimes we forget to imagine the effect our word picture could have on our audience which is a tad frustrating. Mainly it is frustrating because I cannot understand enough to help in any measurable way due to the loss of the message I suppose. Good thread.
