Explain the central symbolism in "Hills Like White Elephants" by Hemingway.

The
central symbol in "" is the setting, with the hills in the distance. One side of the
train station in Spain is covered with vegetation and fertile while the other side is devoid of
vegatation and stark.  As the conversation unfolds between the man and Jig, it is seen that the
fertile side of the setting symbolizes the point of view and feelings of the Jig while the
barren stark side symbolizes the point of view and feelings of the man. It further symbolizes
the ultimate resolution of thier conversation, which is only hinted at. The train rails separate
the two sides of the setting, thus symbolizing that the rails of disagreement will persist in
dividing Jig and the man as thoroughly as the trains rails divide the fertile land from the
barren. In addition, the hills symbolize Jig's ability to still see the romantic optimistic
potential in the realities of life although the man's response to her ("I've never seen
one") indicates a refusal to think of anything other than the practical and objective. Thus
the hills symbolize the nature of the divide between them, what can now be theirs and what
can't:

Jig: "Then what will we do
afterwards?"

"Well be fine afterwards. Just like we were
before."

"What makes you think so?"
