When in doubt or even not, reading the dialogue aloud like this is a play can really help you catch the rhythm. People's dialogue has a rhythm and each person's is a bit different. Do they use a lot of uhs or ers. Are the words stretched out. There are ways of showing this. If you read the bits of dialogue aloud, youcan show the rhythm on paper. For example. I want uh you uh leave. Says one thing. If someone says. Leave. Now. That says something quite different. Reading aloud can also sshow you how the dialogue is perhaps too long and wandering or one that says words but has no meaning. So become an actor and become your characters.
