" Conversation is clearly one of the most difficult parts of the story. It is not enough to let your characters talk as people usually talk because the way people usually talk is extremely dull. Your characters are not going to stammer, or fumble for words, or forget what they are saying, or stop to clear their throats, at least not unless you want them to. Your problem is to make your characters sound as though they were real people talking (or, more accurately, that this is “real” conversation being read by a reader; look at some written conversation that seems perfectly smooth and plausible and natural on the page, and then try reading it aloud; what looks right on the page frequently sounds very literary indeed when read aloud; remember that you are writing to be read silently).
