I put pen to paper to convey what I cannot by way of speech. Inherent in writing is more time for thought preceding the actual expression, whereas in conversation, words (my words) come out hastily in a somewhat less deliberate fashion and I make more mistakes in context and grammar. Body language and gesturing are often used to complete the thoughts, very much so in my case. In writing, the words have to and do stand on their own. There is no help, no support by way of gestures or facial expressions. As well, that type of support isn’t needed.
Time isn’t as precious in writing. With speech, there is more urgency in communicating ideas. One doesn’t have the luxury of time. Maybe that is why some prefer to write, as I do, and communicate better via written words than spoken. Time affords more confidence in transferring that which I want to deliver to the recipient. Control of that which is exactly conveyed, without any visual disturbance to the receiver from the writer, is greater when writing my words as opposed to speaking. The increased time and control are often necessary for the writer. Both are needed luxuries for this stumbling writer, one to whom writing is preferred.
