Subtilty in "Hills Like White Elephants"

I really enjoyed "Hills Like White Elephants" for 2 reasons: 1. I enjoyed the subtile way in which the two characters talked about an abortion, without ever mentioning the word abortion, and 2. I enjoyed the way in which the author characterized these two characters through their speech. The majority of the piece does not explicitly say who is speaking, but as a reader it is very easy to tell because these two characters are so different. They both want different things, the man wants the woman to have an abortion, but he does not want to force her into it. He wants her to want to have one. The woman on the other hand does not want to think about it at all, instead she just wishes that she never got pregnant in the first place. The author is able to show us this simply through dialogue. I personally often struggle writing dialogue and I found that this piece was a great example of dialogue done well. It not only helps move the plot forward, but it also helps to characterize the characters, in this case it is pretty much the only thing in the story that is characterizing the characters.
