Final answer:
Marji's behavior upon returning home is characterized by emotional distance and cold efficiency in social interactions, notably with her cousin Bernice, revealing a self-assured yet detached personality.
Step-by-step explanation:
Analyzing Marji's behavior when she returns home reveals a nuanced character who is distant and cold in her interactions, especially with her cousin Bernice. Through various passages, it's evident that Marji, who does not see much value in the conventional qualities of femininity, such as giggling and sharing confidences, holds herself apart from others. She comes across as bored or disinterested in others' emotional displays, and tends to address situations with a cold efficiency, such as offering her own allowance to Bernice to solve a problem rather than providing emotional support.
Moreover, Marji is portrayed as someone who is self-assured and does not easily exhibit vulnerability. Her behavior indicates that she prioritizes her own perspective and seems disengaged from typical social interactions that involve sharing and empathy. Bernice, on the contrary, longs for a deeper connection and emotional exchange, something that Marjorie does not provide. Marji's dialogues and actions suggest a character that is self-contained and possible indifference to the emotional wellbeing of those around her.
