If there was one ability I wouldn't mind going without, and would sometimes even rather do without, it's the ability to speak.
Why bother with speaking, when there's a superior form of communication - writing? Why choose to voice out sentences that are not even fully formed in your mind? For that is how most people get by when they make conversation - conceptualise the ideas as they communicate them, not before. Why choose such an inferior, unpredictable form of communication when you can plan out and present your idea in a clear, concise manner in the written form? Surely the half-formed garbled sentences can never do you sufficient justice.
True, even in writing, one can ramble on muddleheadedly, as I have just done, but at least, I have the satisfaction of knowing that that is exactly what I want to say at this moment, and that it's in some semblance of good English, and not the occasional broken sentence I manage to ejaculate on occasion. But forgive the digression, if you will, and allow me to continue with my tirade.
Why choose to communicate verbally when it gives you so little time to adequately ponder over your words? When writing, you have to opportunity to decide and filter and dissect your thoughts and only write what you want others to read. When you speak (unless it's a prepared speech), you scarely have time to form a proper sentence before it has escaped your mouth, never to be undone, or deleted, or canceled out with a neat rule and pen mark. Saying things like 'I go with you' instead of 'I will go with you' are slips which are only too easy to make when you speak, but which seldom occur when you write. Sometimes, you let go of a sentence before it's even formed, and your brain doesn't work quickly enough to fill in the blanks, leaving you trailing off with a helpless look in your eyes, and a 'you know what I mean' shrug. When you write however, you can form these wisps of sentences, and yet still fill in the blanks before the reader has a chance to see your weakling of a sentence.
Why choose to communicate verbally when you can actually finish an argument or an idea without someone interrupting, and breaking your flow of thought? Sometimes you never even get a chance to express a point of view, let alone and argument, over the clamour of voices. In writing, however, you can be sure that you've 'said your say', and be content in the knowledge of having made a proper case for your stand. True, you can refute the points other's bring up immediately when you speak, but you can always adress them with additions to and editng of your essay when you write.
But the worst thing about speaking is the way it's all too easy to betray your emotions. You can unintentionally let a bitter word slip that destroys relationships and ruins lives. You can betray your fear and upsetness when you speak. It's much harder to distance yourself. When you write, it's a different story altogether. You may be crying when you write, but in your writing, if you do not intend to show your emtional upheaval, it won't be detected easily by your reader. You can maintain a seemingly calm, collected, logical, unemtional stand, or discuss sensitive issues without revealing that you are het up about them. In fact, you can address more sensitive issues, because when speaking verbally, you may be so choked up with emotion that you cannot dislodge the lump in your throat to talk, but it doesn't mean that you can't think. And what you think can be written down easily enough. It's not likely you can be so choked up you can't move your hand. In no way are your tear ducts related to your hands, at least not in any way that I can see at this moment.
True enough, speaking is faster. Perhaps communicating verbally is also more spontaneous and hence, more exihilarating form of conversation. Verbal slander, if you're into slander at all, is also less "serious" than written slander. So in that sense, the temporal nature of speaking is advantageous to some.
But even though speaking may be convenient, and perhaps I might even go so far as to call is indispensable, I still cannot help but wish sometimes, that I was mute. It would make verbal communication irrelevant.
