When you write conversation, begin a new paragraph each time
the speaker changes.
A lot of aspiring writers seem to shy away from this one. They think it leaves too many gaps, too much white space on a page. What it really does is
add clarity.
We're not at school where some obsessive monitor begrudges handing out extra paper.
But if you have a whole page of single-sentence rapid-fire dialogue it does start to look a bit like a contents list or a recipe,. If you chuck in an an occasional 'action tag' it breaks things up and keeps it more interesting. It also helps prevent the reader losing track of who is speaking. (There's a lot more to be said about
that problem, but we'll keep it for another time.)
Let the speaker turn away, or make a violent hand gesture. Pick the right action and it also reinforces the words. Just don't overdo the description.
