Human stories are practically always about one thing, really, aren't they? Death. The inevitability of death. . .. . . (quoting an obituary) 'There is no such thing as a natural death. Nothing that ever happens to man is natural, since his presence calls the whole world into question. All men must die, but for every man his death is an accident, and even if he knows it he would sense to it an unjustifiable violation.' Well, you may agree with the words or not, but those are the key spring of The Lord Of The Rings
That's what we storytellers do. We restore order with imagination. We instill hope again and again and again.
The worst of such stories is that the triumphant romancers can always be put to confusion and crushed by the very details in which real life is so rich and which these unhappy and involuntary story-tellers neglect as insignificant trifles. Oh, they have no thought to spare for such details, their minds are concentrated on their grand invention as a whole, and fancy any one daring to pull them up for a trifle! But that's how they are caught.
