isaiah had returned from washington the night before and promised he would n't talk politics until after dessert , so they ate and drank and chided the children when they got a little too boisterous and the talk jumped from the latest picture shows to pop u lar books and songs and then to the rumor that war radios would become a consumer item that would broadcast news and voices and plays and songs from all over the world , and luther tried to picture how a play could be performed through a box , but isaiah said it was to be expected .
