A robot does not usually feel; the very term "robot" itself has origins in unthinking “drudgery” and “servitude.” One of the story’s many ironies, then, is Klara’s simultaneous status as robot and her remarkable ability to sense emotion. During the trip to Morgan’s Falls, the Mother and Josie start a discussion about her capacity for feeling:
‘It must be nice sometimes to have no feelings. I envy you.’
I considered this, then said: ‘I believe I have many feelings. The more I observe, the more feeling become available to me.’
She laughed unexpectedly, making me start. ‘In that case,’ she said, ‘maybe you shouldn’t be so keen to observe.’ Then she added: ‘I’m sorry. I didn’t mean to be rude.’
This exchange spotlights the central surprise offered by Ishiguro’s novel. The story’s portrait of Klara steers clear from the popular cliches that feature unfeeling or malicious robots. Klara is capable of feeling, thanks to her powers of observation. She not only feels but understands the messiness of the human condition. Klara can sense the innate “goodness” in the children, despite their behavior at Josie’s interaction meeting. She feels sadness at the sight of the dead Beggar Man and joy in the reunion between the Coffee Cup Lady and the Raincoat Man, people entirely unrelated to her. Klara’s sensitivity is so expansive that she seems more emotionally attuned to those around her than the humans themselves. Her sensitivity contrasts against the Mother’s neediness and, in this exchange, the crudeness of her suggestion—a point-blank denial of human feeling.
Irony mingles with sadness in Part 6 of the novel, as Klara reveals to the reader that she is no longer with Josie:
Even so, such composite memories have sometimes filled my mind so vividly, I’ve forgotten for long moments that I am, in reality, sitting here in the Yard, on this hard ground.
Beyond the bitter surprise of this discovery, this admission is ironic. Klara’s only foe—if there is any—shapes up to be the Cootings Machine, the struggle against which drives the greater part of the novel’s plot. Believing Josie’s sickness to be caused by the Sun’s dismay at the machine’s Pollution, Klara intends to save Josie by destroying the machine. She prays to the Sun and tracks one down with the help of the Father, even offering her own P-E-G oil to destroy it.
So obsessed with stopping the Cootings Machine, her war against these instruments of construction only makes her eventual abandonment all the more unexpected and ironic. Klara destroys a Cootings Machine that sits in the ramshackle lot. She ends up in just this kind of Yard herself, a dumpster of sorts where pieces of machine or “dented grille panels” lay in rows. She suffers the same fate as the thing she destroys. The novel’s outcome suggests that, however much Klara tries to prove her use, she is unable to separate herself from the less favorable connotations attached to technology and machinery.
