Write a story about "Hills Like White Elephants" after the original story ended.

This is a really interesting assignment. The way you write it depends on what you think Jig, the protagonist, will do after she gets on the train for Madrid. At the end of the story, it is unclear whether she will get an abortion or not, in spite of the fact that her boyfriend seems to be urging her to do so. She has reservations about the subject, but she seems to be leaning in that direction.
When you write the story, you can write the conclusion to this question. Will Jig get an abortion or not? If she does, how will she feel about it? Will she be able to continue in a relationship with her boyfriend? If she does not get an abortion and has the baby, will her boyfriend stand by her? How will she raise the baby? You can go in a lot of interesting directions with this story.
Be sure to stay true to Jig's personality, which is conflicted and self-effacing (she tells her boyfriend that she does not care about herself). Has she grown as a character since the end of the original story? If so, explain in which ways (for example, has she become more self-assertive?).
