This story is written in the first person, and the narrator is also the protagonist in the role of the yellow wallpaper. This point of view works for this work because the Narrator writes in his diary during these three months at the House. This immersion in the brain of a Madwoman is nice to see how she goes crazy. But we must remember that a crazy narrator is not a reliable narrator. It's about a woman who is trapped in the role of your room, something that clearly can't be real. The Shmoop site sees that even though it says many things, false things, they are so strange that we know the truth about it. That's why this unreliable narrator still serves to tell this story. This point of view and narrator's voice are used because they work well for this sarcastic work. Barbara Welter mentions in her article that the way of writing is a bit frivolous, has a childish tone, but because of this weak mind women's thinking is well represented. We follow him in his madness because we read how this woman thinks. Furthermore, we feel empathy for her because we know that your rest cure isn't working, that her husband doesn't care much, and that there's not much she can do to keep from going crazy. Their situation is so tragic that we identified with it, otherwise the author uses it to fulfill his purpose
