"Hills Like White Elephants" response

This story was very vague.  The girl, Jig, is pregnant and the "American" man with her is trying to convince her to have an abortion.  The first thing I noted in the story is that Hemingway refers to the "girl" as a girl and the "American man" as a man.  Why has he not referred to the girl as a woman?  She is obviously old enough to conceive a child, but the initial image in my mind was a man and a child girl.  Instead it turns out to be a man and a woman.  My second notation was the location of these people.  They are travelling from Barcelona to Madrid, Spain and the beginning of the story states their whereabouts, the Ebro valley.  It also states that they are waiting for a train to Madrid.  Then at the end of the story the man carries their bags to the other side of the tracks.  So, initially they are traveling east to west and then decide to go back east to Barcelona.  I am assuming that this is where she is going to have the abortion done and initially attempted to run from the procedure by getting on the train to Madrid.  Also, the fact that they were in Europe at the time of this discussion about abortion didn't escape me.  I am sure that it was intentional for Hemingway to place the setting in Spain rather than in the United States.  Possibly because of the legalities of abortion in the 1920s in the U.S.?  The conversation between the two characters was slow at first, but once read closer it shows that the "man" is from America, yet he speaks Spanish to the waitress.  The "girl" speaks no Spanish and her place of origin is unknown.  She is obviously not from Spain.  It is easier to understand this story with a little information about Hemingway's intentions, but without a little extra research it could be read as pointless dialect between two characters.
