Answer:
Well, this will highly depend on the context, but here are some possible explanations.
Step-by-step explanation:
1. The narrator could have mentioned the lack of a chandelier in her room to show that she is in poverty. (This seems like that is why she included but I am not sure)
Chandeliers are usually in fancy mansions and houses.
2. This could be an expression to her being lonely.
A chandelier is usually present during a big ball or special party. (Princess setting)
Those are my best guesses without context, it could be countless other things depending on the story. hope this helped you.
Just one last example it could be because the environment changed and the character is reflecting the change. Like she used to have a chandelier in her room, but now she lives somewhere else, and it is gone.
