Is it better to do it like this? Where the conversation begins and ends the same paragraph? "All set my boy." he replied, almost hissing the words out. Mako fought the urge to grind his teeth. "I'm not your boy." Or like this? Where you start a new paragraph when the character speaking changes. Like so. She folded her arms across one another and stuck her tongue out, pleased with herself. "You can do better than that." she teased. The boy would have shouted an insult at her if the massive boulder he held up with both hands didn't just make him tip backwards onto the dirt. "Owww..." he groaned. She walked over to the boy while shaking her head in disappointment. She nodded at the boulder. "Again." Or are there other ways you prefer? I'm just wondering because I seem to switch between the two depending on which one suits the scene better.
