I don't agree with Willa Cather's comment, because I think that there is an infinty of human stories. Everybody will have it own. If there were only two or three, everybody will see it and try to make it different. But has I said, there's and infinty of possibilities : It's every time different. And if sometimes you can see that it seems the same, there's always a difference, even if it's little, it can make the difference.
Hope it helps.
