Two men and a woman were in the room when they arrived.  These left shortly, leisurely, severally, and unostentatiously.  After that they were alone, except that they were both served with Jubal's favorite brandy - by hand, to Jubal's pleasure; he was quite ready to agree that the remote control these people had over objects around them was a labor-saver and probably a money-saver (certainly on laundry! - his spaghetti-splashed shirt had been so fresh that he had put it on again today), and obviously a method much to be preferred for household convenience to the blind balkiness of mechanical gadgets.  Nevertheless he was not used to telecontrol done without wires or waves; it startled Jubal the way horseless carriages had disturbed decent, respectable horses about the time Jubal was born.
