“I tried to imagine me and Rosa getting so angry with each other we would start to fight like that, actually trying to damage each other’s bodies. The idea seemed ridiculous, but I’d seen the taxi drivers, so I tried to find the beginnings of such a feeling in my mind.”

This quotation occurs towards the beginning of Part 1—Klara has just seen a physical fight between two taxi drivers and is wondering if the level of anger felt by the two men would even be possible for her to feel. In this moment, she is working to define her limitations as an AF, to understand her similitude to humans and just how much she is capable of experiencing the emotions that they do. This event happens when Klara and Rosa are having their turn in the window, and Klara is quickly growing adept at recognizing and understanding human emotions. Although she states that she wishes to do so in order to one day better serve the child that chooses her, her exuberant curiosity appears more human than robot in itself. Klara’s quest to understand humans sets her apart from other AFs like Rosa and Boy AF Rex. Her interest in humanity is what makes her become even more human than most AFs already are, turning her into an individual character rather than a robot built just like all others. 

However, Klara ultimately cannot relate to the anger of the taxi drivers. While she can often find comparable emotions within herself for other human feelings, destructive anger is not one of them. This limit distinguishes her from humans, and makes the point that the ability to feel anger may be a distinctly and innately human trait.
