Which of the following lines from "in another country" by ernest hemingway contribute to the prevailing mood of apathy in the story?

There are two lines that contribute to the mood of apathy:

A. One day I had said that Italian seemed such an easy language to me that I could not take a great interest in it; everything was so easy to say "ah yes" the major said. 

AND 

C. We were all a little detached, and there was nothing that held us together except that we met every afternoon at the hospital.

Apathy, which means to not care and/or to be somewhat stoic with regard to something, can be found in response A in how the narrator notes that he could not take a great interest in the Italian language. An element of apathy can be found, too, in response “C” in how it is noted “We were all a little detached.” Both responses contain the theme of not caring, not interested—apathy.
