In our daily life we take the word friendship too lightly, and we confuse the words "friend" and "acquaintance." An acquaintance is someone whom we have met, and he has seen us, and we recognize one another. We may have been introduced at a dinner party. We use the word "friend" so freely in everyday language that we have forgotten the meaning of it. Generally we call anyone whom we have seen at a reception or party a friend; or anyone that belongs to our club. But even to have one friend in one's life is the greatest good fortune.
