From “The Yellow Wallpaper” by Charlotte Perkins Gilman:
“There is a recurrent spot where the pattern lolls like a broken neck and two bulbous eyes stare at you upside down. I get positively angry with the impertinence of it and the everlastingness.”
Impertinence is used to show that the protagonist of the “The Yellow Wallpaper” is noticing features in the wallpaper, and applies human-like traits to it. She believes that the eyes in the wallpaper are staring at her in a rude way.
