Communication is such a central part of our lives that we tend to take it for granted, it fades into the background, like the wallpaper. That is perfectly normal, but it can also be problematic. Consider language, for example. We largely live our lives through language. Much of our work is through language; we form relationships through language; we fall out through language. Much of our leisure time is enjoyed through language. Imagine, for example, trying to go for, say, a week without using language. We wouldn’t get very far would we? (not least because we tend to think through the medium of language).
But the way we use language can be problematic. Misunderstandings are very common, sometimes with minor consequences, sometimes with major harm as a result. This especially applies to written language. This is because when we speak, we use a very complex and sophisticated system of intonation – that is, we can generally understand what people mean from not just what they say, but the way they say it (the tone and pitch, for example). In writing, though, the nearest we have to this sophisticated system is punctuation and that is a poor substitute, even when people use it properly (and, of course, many people don’t). Consequently, the scope for misunderstanding and ill-feeling is much greater when we communicate in writing.
