These interactions may seem silly, but their implications are profound. McClure recalls one toddler who was trying to feed raisins to her grandfather through the screen of the iPad on which he appeared. The little girl would walk around the iPad with a handful of raisins and look for him. She’d also leave raisins for him there, behind the screen. Her mother tried to help her understand that although the man appeared on the screen, he actually lived in another house some distance away. “The mother kept saying, ‘Where does Grandpa live?’ And the little girl pointed to the screen and said, ‘Right there!’ And in a sense, that is where he lives. When you want to see Grandpa, you go to the screen and ask for him.”
