Can you please help me to find the themes and/or thesis of "Hills Like White Elephants" by Ernest Hemingway?

's short story "" is an iceberg of
a narrative; a story in which practically all the drama and tension is below the surface. The
action is almost non-existent: A couple wait at a small railway station for the train to Madrid,
order drinks and discuss whether the girl will have a "procedure" or not. That is all
that happens. Beneath the surface, however, is all the guilt and trauma attached to abortion
(illegal in most European countries at the time and particularly taboo in Catholic Spain) and
the misery of a failed, unequal relationship. The story comes from a collection called
, a bitterly appropriate title given the isolation of the two central
characters.

There are a myriad of themes: the sterility and boredom of
relationships in the modern world, the conflict of reason and emotion, the poverty of a life
without values or attachment. The man in the story is perfectly reasonable, but Hemingway seems
to be pointing how reason such as his is an unsatisfactory standard by which to live. A life
which might seem enviable from the outside, that of a rich man without responsibilities, with
nothing to do but see new sights and try new drinks, is in fact so hollow and meaningless that
it is bound to degenerate into squalid, miserable scenes like this one.
