Revising Business Messages

   How are speakers different from writers in the way they emphasize ideas?

Speakers and writers have different tools to emphasize their ideas.  A speaker can and has to do some extra work beyond just saying the words. While speaker is able to change a tone of his/her voice, use facial expressions, a pose, put a stress on the key words and it might mistakenly look that a writer deprived of such eloquent features. There is a big space for writers to be not less expressive. There are many kind of writing techniques, for instance, playing with a text structure, with the sequence of ideas and the way they disclose, describing the main topic in a certain way and with certain words that makes us think the way that the author wanted to  make us believe.

  Why are short sentences and short paragraphs appropriate for business communication?

Short sentences and short paragraphs are appropriate in general because the main function of any business letter is informative. There is nothing common with your personal opinion or analysis of satiation unless you were asked to do this research. I think it is important to care about time which your receiver has to spend reading your message and how much valuable information he or she can get from this reading.

      When might it be unethical to use the indirect method of organizing a message?
Usually the indirect form of a message is used when the subject of a message is not really pleasant for instance it might be refuse of requests, reject claims or some kind of sensitive messages which have to respect the feeling of the audience and minimize a negative reaction. I think it is unethical to use indirect way of writing when people wait some kind of action, some information, some urgent instructions because it puts them in quandary.
