Okay, I'm a screenwriter, and one of my characters is discussing having a bad marriage. At some point in the dialog the character needs to ask to change the subject but in a way that doesn't make her seem insecure or afraid of talking about it. It has to be something on the order of: ...Blah, blah... I'm sorry I don't want to talk about it anymore. What do you want to talk about? It has to merit a "what do you want to talk about?" type of question. The best I've come up with is: ...Blah, blah... Okay, New topic. What do you want to talk about?
