I agree with George Orwell that language should be an instrument which we shape for our own purposes. The use of language is the way people express themselves. And every person is an individual. There are several different ways that a greeting could be said. For instance, a person might say "hello" or "hi" or "hey". They could even say "what's up?". All four of these greetings mean the same thing however they all have a different tone. In order from left to right each greeting gets more casual. Depending on the personality of the person or how they want other people to perceive them, dictates the difference in their use of language. Language can create an image for oneself. If a person wanted people to know that they were laid back and friendly they might choose to say "what's up?" over other options. This is why language is a instrument--because the words create the sound of music (the tone) that the user wants people to hear.
