Even though Rosicky has been diagnosed with a failing heart, nothing about his outside appearance would indicate as much. His literal heart may be weakened, but his emotional heart—his love, kindness, and generosity—is still strong, so much so that Rosicky being sick seems almost inconceivable to Mary. Mary, like Rosicky, sees their lives as happy and fulfilling. While immigrating to the U.S., managing a farm, and earning little money are all challenges, the couple has been happy throughout all of this because their worldviews are compatible, and they support each other. Mary’s thinking also highlights a key difference between city and country living: she believes that the countryside has made her tougher, while the city made Rosicky more compassionate.
