QUOTE : To say exactly what one means, even to one's own private satisfaction, is difficult. To say exactly what one means and to involve another person is harder still. Communication between you and me relies on assumptions, associations, commonalities and a kind of agreed shorthand, which no-one could precisely define but which everyone would admit exists. That is one reason why it is an effort to have a proper conversation in a foreign language. Even if I am quite fluent, even if I understand the dictionary definitions of words and phrases, I cannot rely on a shorthand with the other party, whose habit of mind is subtly different from my own. Nevertheless, all of us know of times when we have not been able to communicate in words a deep emotion and yet we know we have been understood. This can happen in the most foreign of foreign parts and it can happen in our own homes. It would seem that for most of us, most of the time, communication depends on more than words.
