can be tricky. Its not a few words here and there its the whole chunk of dialogue that has to work. I am still slogging away at my re write of chapter three which has a fair bit of dialogue, and difficult dialogue to boot in that it aims to show an awkwardness between two characters meeting for the first time. I am re writing POV from one characters(original draft) to anothers(my protagonist) which is taking time to get exactly right. Should be there in another session though I hope.
