Read this excerpt from a doll's house by henrik ibsen.
nora: more than anyone else. i know you are my truest and best friend, and so i will tell you what it is. well, dr. rank, it is something you must me to prevent. you know how devotedly, how inexpressibly deeply torvald loves me; he would never for a moment hesitate to give his life for me.
rank: (leaning towards her) nora, do you think he is the only one?
nora: (with a slight start) the only one?
rank: the only one who would gladly give his life for your sake.
nora: (sadly) is that it?
rank: i was determined you should know it before i went away, and there will never be a better opportunity than this. now you know it, nora. and now you know, too, that you can trust me as you can trust no one else.
nora: (rises, deliberately and quietly) let me pass.
rank: (makes room for her to pass him, but sits still) nora.

why do you think nora stopped the conversation?
