The story of an hour is a feminist novel by Kate Chopin; here Chopin uses both ironic and serious twists and foreshadows to express the women were eager for freedom and hope to get over with the inherent oppressiveness of marriage.
The women back then desire very much freedom, in the story although that her husband is dead, she is secretly happy, she began to realize that she was free. Yet even though they want it so badly, they cant have it, even though seemingly looking in from the outside she had everything, but not freedom. These implicitly make a claim to the generality at the society scale.
This novel raises people thought to marriage, its clear that the male domination of the time was oppressive. The women are nameless at that time; also they have no rights, no power, and no freedom. This could explain why that when she suddenly clear that she isnt imprisoned anymore she cried with glee in her heart. She was drinking in a very elixir of life through that open window. Elixir: a medicine regarded as a cure for all ills. She was sick, sick of the prison, and now she is cured.
Chopin foreshadowed that Mrs. Mallards soul and body and connected. Into this she sank, pressed down by a physical exhaustion that haunted her body and seemed to reach into her soul. "Free! Body and soul free!" She kept whispering. So we arent surprised when her soul dies (thats when her husband is back) her body dies (heart disease).
Chopin used an ironic and serious twist (When the doctors came they said she had died of heart disease --of the joy that kills.) to complete the ending. This express even more that she will never be truly free unless the society has a big change in the way that they look at women (which doesnt happen until far later) die is her only way to relief.
In the story after the natural sadness, her heart is filled with glee or a monstrous joy because she sees her life as a new, independent life. This extreme reaction is due to the inherent oppressiveness of marriage and the societys prejudice of woman.
She hoped for a better independent life, but her husbands return just took that away her one hour freedom, thus killing the womans fragile heart.
