The Yellow Wallpaper

Having read this story just lasxt semester for Comp class, I already had the basic story figured out and getting to look over it again helped pull some new details out of it, the main one being the ending, which i apparently just skimmed through. The part where she starts thinking that she is actually one of the women in the wallpaper who has escaped from her wallpaper prison and refuses to go back in was new to me and i'm not sure how i missed it the first time through. One of the best points that was brought up was, if her husband and his sister do not want her to write, what is the likelihood that they would have left anything in there for her to write on and if they didn't do that, then what is she writing all this down on? she notices areas where the wallpaper has been torn off and thinks that the women behind the wallpaper keep moving it at night because the pattern starts looking different, but i think its because she keeps removing pieces of it to write on.
