I'm writing a short story where the opening scene is an argument between a couple. The woman is complaining that the man doesn't appreciate her any more, that he never says 'thank you' or shows his appreciation in any way. She says he's become complacent after twelve years together and she's had enough, and after alot of posturing and thrashing about she finally walks out on him. My problem is I don't know how to progress with the argument. I'm having trouble with the dialogue. How does the man reply? what does he say to try to appease the woman? how does she react to this? Baring in mind he has to do badly because she leaves at the end of the scene. Can anyone help?
