Sophie attempts to shift the conversation toward a safer topic by asking the Giant if he likes vegetables. Her intention is to redirect the dialogue away from the unsettling subject of humans, which the Giant is keen to discuss. He responds firmly, emphasizing that humans are far more interesting than vegetables and insisting they continue talking about humans.
This exchange highlights the tension between Sophie’s desire for a lighter discussion and the Giant's fixation on the nature of humans. It reflects the overall theme of the story, where food serves as a metaphor for the deeper dynamics between the characters and their differing views on humanity.
