Hills Like White Elephants

The conversation where the two characters are disagreeing with one another stood out the most to me.  In a way, the dialogue in this particular area reminded me of the song "Viva la Vida" by Coldplay.  Most likely, there is no direct correlation.  The female character stated that they could have the world, whereas the male character stated that the world was theirs in the beginning but it was taken away.  In a sense, he might be saying that it's time to move on, whereas she wants to dream something that potentially will never happen.
