Mrs. Graue was busy at her desk when Josh's mother came into the room. Mrs. Graue looked up at this stranger and said, "Do you want something?" Josh's mother, who was clean 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?
