Two Questions. help!!!

4. What kind of relationships do the Mallards have? Is Brently Mallard unkind to Louise Mallard, or is there some other reason for her saying "free, free, free!" when she hears of his death? How does she feel about him?

5. Mrs. Mallard closes the door to her room so that her sister Josephine cannot get in, yet she leaves the window open. Why does Chopin make a point of telling the reader this? How might this relate to the idea of being "free" and to the implicit idea that she is somehow imprisoned? Do other words in the story relate to this idea?
