I recently read Joseph Conrad's novel An Outcast of the Islands and he had a scene where a character was talking simultaneously to both his little daughter on his lap and some lackey standing before him. Each sentence was directed to one person, then the next to the other. It went on like this for a half dozen sentences in one paragraph. It was easy to figure out to whom each sentence was directed given the context, but I thought it was masterful on Conrad's part to lay it out like that.
