[2] Two young men, a mechanic, Dave, and a medical student, Phil, collaborate on modifying a household robot, originally meant only to cook and clean.
Dave initially avoids her and rejects her advances, but after some time he marries her and they live together on his farm.
Over the years Phil assists her in artificially aging her features to match the changes that occur in her human husband.
When Dave inevitably dies, she sends a letter to Phil saying that she intends to drink a powerful acid which will destroy her internal metallic structure and will appear to be suicide by poisoning.
In the final line it is revealed that Phil, who has been narrating the story, had secretly been in love with her the whole time.
