Don't become a great thinker. Decide what the scene is supposed to say, from the author's point of view , not your own. A casual conversation is not a scene. A scene is a struggle of wills , a contest , a kind of combat. Don't make negative choices.
Audiences lose interest in characters who give up.
The person the audience is rooting for. The person they are against. That's the question that decides the staging. The pattern of behavior. It's telling the story in movement.
