Juxtaposition in "Solder's Home"

In "Solder's Home" Hemingway presents a strong juxtaposition with the protagonist, Harold. In this story Harold likes the German and French girls who he has taken photographs with, however he doesn't like any of the American girls. Harold likes the looks of the American girls better than the looks of the German or French girls, however he doesn't like the fact that they are all "complicated" and like to talk. Harold enjoyed being with the American girls more than the French or German girls because none of them talked. This juxtaposition is important because it shows that something is wrong with Harold that makes him not want to talk about his past or about anything in general. It also shows that Harold doesn't really care about anyone else. The juxtaposition really shows the emphasis of the effect that the war had on Harold more than other techniques could have.
