Mrs Graue Was Busy at Her Desk When Josh's Mother

Mrs. Graue was busy at her desk when Josh's mother came into the room. She looked up at this stranger and said, "Do you want something?" Josh's mother, who was cleanly but poorly dressed asked, "How is Josh doing in school?" Mrs. Graue responded with a succinct report, indicating that Josh was quiet and did not bother anybody. She added that he could pay attention better during group time than he had been. Then she looked at her watch. Josh's mom nodded her head and left. She did not return to school again. Who should be held accountable?

A) The mother, because parents should be expected to call ahead for appointments.
B) The mother because not attending other functions indicated her lack of interest.
C) The teacher was responsible because her responses were unfriendly and indifferent.
D) The teacher because she knew so little about Josh.
