OLM+So+dawn+goes+down+to+day

So dawn goes down to day: I think that the author is trying to say that the good parts of life, go into reality(day), in which everything is not perfect. I think that the author is also saying that there are good things in life(gold), but they don't always stay the way you want them too.

Good point, Olivia. I agree that this is Frost's message.
