Sheila's initial response to Eva's death was to question her beauty, suggesting that Sheila's grief was greater because Eva was pretty. This highlights Sheila's flawed worldview, where the value of someone's life is tied to their appearance. This idea extends to social classes, as the wealthy can enhance their beauty with better clothing and makeup. Therefore, Sheila's evaluation of people suggests that the upper classes are more valuable than the lower ones. Priestley's intention is to create a negative perception of Sheila, portraying her as shallow.
