Without the letters of condolence, telegrams of congratulations, and occasional postcards, the friendship of a separated friend is not a social reality. It has no existence without the rites of friendship. Social rituals create a reality which would be nothing without them. It is not too much to say that ritual is more to society than words are to thought. For it is very possible to know something and then find words for it. But it is impossible to have social relations without symbolic acts.
