Final answer:
The perception of the Tomkeys as not 'normal' leads to exclusionary behaviors, reflecting themes of discrimination and emotional impact on those perceived as different.
Step-by-step explanation:
In the excerpts provided, the notion of what is considered "normal" varies across different narratives, reflecting societal, historical, and personal tensions. These tensions result in exclusion, mental turmoil, and a revelation of personal or systemic issues. For example, perceiving the Tomkeys as not normal in "Us and Them" likely leads to discriminatory attitudes or behaviors from the narrator, underscoring a theme of ostracism and the consequent emotional impact on both the individual and the group perceived as different. These themes resonate across the extracts, revealing deep-seated biases, the struggle for acceptance, and the various ways individuals and groups cope with being labeled as outsiders.
