In the short story "The Doll's House", what does the narrator reveal about Aunt Beryl's attitude toward social classes?

Aunt Beryl sees herself as above all others because of her social status. She believes herself entitled to the luxury in which she lives and detaches herself from everything and everyone outside of her self-proclaimed realm. Poverty isn't welcome in Aunt Beryl's world, and when it appears..... she's quick to rid herself of it.

At the back door stood Aunt Beryl, staring as if she couldn't believe what she saw.
"How dare you ask the little Kelveys into the courtyard?" said her cold, furious voice. "You know as well as I do, you're not allowed to talk to them. Run away, children, run away at once. And don't come back again," said Aunt Beryl. And she stepped into the yard and shooed them out as if they were chickens.
"Off you go immediately!" she called, cold and proud.
