why did bruno think the fury was the rudest guest he had ever witnessed ?/

Mother had cleaned the house frantically to prepare. Father had prepared Bruno and Gretel for the Fury's arrival by telling them, "it is very important for my career that tonight goes well" (119). When the Fury had arrived, he was with a woman named Eva. In contrast to the Fury's brusque hostility - he was "the rudest guest Bruno had ever witnessed" - Eva had been kind to the children and had smiled at Bruno before the Father closed the door to the dining room (122). After the Fury and Eva had left, Bruno had overheard his parents' conversation about leaving Berlin. Days later, he had arrived home from school to find Maria packing his belongings.
