I've been thinking today about the curious disconnect that exists between the act of producing writing and the act of consuming it. Artists of other media have the potential to watch their art being consumed. A singer can look out on the audience as she sings. A painter can stand in the gallery as people look at his paintings. A movie director can sit in the movie theatre and see if the audience is laughing or crying where he intended.
While a writer can read his work out loud, for the most part this is just a variant of acting; he's reading a script, and the success of the reading will depend not just on the words but tone, inflection and body language.
But the one thing a writer would almost never have the chance to do is to watch someone sitting silently reading his book. I suppose it could happen every now and then by chance that a famous author might be on a plane and spot someone reading their latest best seller. But, even then, reading is such a silent, internal process... how does the writer know what the reader is seeing and hearing as the pages turn?
Each story we write is only a message in a bottle. We will never know where it may wash ashore.
