What is maria's primary fear regarding bruno's attitude toward out-with

Bruno decides to speak to Father, who arrived at Out-With a few days earlier. Bruno remembers leaving their house in Berlin that morning - it hadn't looked like their home anymore, with all the furniture and decorations packed up. Before they left, Mother had said, "We should never have let the Fury come to dinner ... Some people and their determination to get ahead" (40). Maria had overheard her and Mother had tried to backtrack, becoming embarrassed. Maria had been embarrassed, too, and had quickly gotten in the car.
