The opening story is about a robot named Robbie, coincidentally enough, who enjoys a fantastic relationship with young girl named Gloria whom he has been programmed to essentially nanny. Gloria is soon the only member of the household that actually seems to be okay with the presence of a robot in the family. Gloria’s mother schemes to get her husband to go the whole nine yards and remove the machine from the equation; a decision which the expected emotionally wrenching effect on the innocent. This opening sets the stage for a theme that Asimov and others will constantly return to in stories about not just robots, but all new technological advancement: a seemingly hard-wired resistance constructed upon emotional rather than logical fear and suspicion about what exact role technology will play in altering our own future.
