As I haven't read the story, I can't say for sure. But the main character is likely the girl the title refers to. There might also be other important characters like her parents, friends, or a love interest who play significant roles in her story.
The story might be about a memorable encounter or a relationship with a girl and the events that unfold around it.
One possible theme could be memory. Since it's about a girl the narrator knew, it might be about how memories of her linger and shape the narrator's present. Another could be the theme of change, as the relationship with the girl might have brought about some kind of transformation in the narrator.
It could be a story about a memorable friendship or a significant event involving her. Maybe it's a tale of her growth and transformation.
I haven't actually read this specific short story. But generally, in a short story about a girl, the plot might revolve around her relationships, like with family or friends. It could also be about her personal growth, dreams, or the challenges she faces in her life.
The main character is the girl who has this excessive knowledge. However, there could be a host of other characters. There might be a love interest who is either supportive or a source of complication. If the story is set in a school or work environment, there could be colleagues or classmates. There may also be authority figures such as teachers or bosses who either believe her or dismiss her knowledge. And then there could be the villains or those with a vested interest in hiding the truth that she has uncovered. These characters would interact with the girl in different ways, either helping her or hindering her journey as she copes with her knowledge.
The main characters in 'Girl' by Kincaid are the mother and the girl. The mother is a dominant figure, constantly giving instructions to the girl.
In Gregory's Girl short story, Gregory is clearly the protagonist. He is an ordinary boy with extraordinary feelings. The girl he likes is also an important character. She is probably someone who is different, perhaps more confident or popular, which attracts Gregory. There might also be Gregory's friends in the story, who could be influencing his actions or providing a contrast to his own personality.
Tana is a main character. She is a girl who gets caught up in the world of Coldtowns and vampires. Another important character is Gavriel, a vampire. He has his own motives and his relationship with Tana is complex.
The little girl is the central figure. Sometimes she has a best friend, which could be another child or an animal. In some stories, there is an antagonist. It could be a bully at school or a mean relative. And there are often adults around her, like her parents who might be strict or loving, which affects the little girl's actions and decisions in the story.
One possible theme could be lost love. If the narrator had a relationship with the girl, it might have ended, and he is reflecting on what was lost.
