This story is about two sisters who have different experiences with a chore which was to get water from the spring that they were sent to do by their Mother. The younger of the two (which the mother doesn’t care for that much) had a great experience at the spring when she was to go get water. She got the experience of helping out an elderly women and got rewarded very greatly for being generous and kind by helping her. The elder daughter was sent to the spring upon request of her mother after her mother had seen what the youngest daughter was awarded for helping. The elder daughter didn’t have the greatest of luck, like her younger sister did. The elder daughter was very rude and not helpful towards the lady at the spring which wasn’t helpful towards her own situation.
The tone of "In Another Country" is sanguine, or hopeful. The speaker of the story feels rather optimistic, despite all the pain and suffering around him. Even during the war, the speaker notices the electric lights that come on along the streets in winter as well as the snow on the foxes’ fur as the wind blows their tails. He also remarks that the hospital, a place filled with pain and injured people, is old and beautiful. When the speaker sees the major’s hand, he thinks it looks like a baby’s hand. These appreciative reflections during a war suggest that the speaker is hopeful. The speaker’s tone, then, lets readers see the war in a less gruesome light.
