The mother is really a static character. She changes a little bit, but not a whole lot. In the beginning the mother's attitude is she really doesnt care about her kids, and all she does is complain about not having money. In the middle, its safe to say she still didnt care because when she started getting the money and started "Careing" for her kids, it was only because of the money. Her attitude never really changges until the end when paul gets sick. so yea i would say, her attitude in the middle is positive compared to her attitude in the beginning because she starts buying stuff for the house and hires paul a tutor.

make sure u mention how the main issue in the story was greed and that paul's mom only cared about money, so paul felt that he needed money to get his mother's love!

hope this helps. its very hard to explain lol good luck with the essay
