Final answer:
Brynleigh made social mistakes with Draycott Deyo due to her unawareness of his religious studies and offended Marjorie by stealing her 'property', likely referring to social popularity or attention.
Step-by-step explanation:
Brynleigh "got off on the wrong foot" with both Draycott Deyo and Marjorie. Not realizing that Draycott Deyo was studying for the ministry and seeking a more reserved girl, Brynleigh unintentionally offended him with her casual and forward conversation. Similarly, she unknowingly made a faux pas with Marjorie by stealing her 'property' which in the context probably refers to social attention or a specific interest, causing Marjorie to feel upstaged or betrayed which led to a feeling of guilt on Brynleigh's part.
The incidents highlight the importance of social awareness and the potential impact of misunderstanding someone's character or intentions. The interactions set the stage for social challenges and the development of self-awareness and confidence in Bernice as she navigated these complex social dynamics.
