Step-by-step explanation:
The narrator in the passage presents a tone that evolves from initial insecurity to admiring and possibly a bit jealous with respect to the other girls at school wearing the hijab. Initially, the narrator is uncomfortable and self-conscious about wearing the hijab, especially during gym class, and tries to maintain a sense of her own identity by styling her bangs to stand out. However, as she becomes more familiar with her peers, she begins to respect those who choose to wear the hijab outside of school voluntarily and admires their courage and confidence, recognizing their ability to express their identity and be respected on their own terms.
