Dance: When Elizabeth and Darcy dance for the first time, their steps and movements are stilted and formal. They are following both each other and the conventions of the dance. This is the symbol of the way their relationships unfolds. They come together by negotiating the cues from each other and by working with the conventions of relationships that determine them.
Likewise, the dance of Elizabeth and Mr. Collins is clumsy and embarrassing in the same way that is approach and his proposal to her.
Outdoors locations: In the scenes which unfold in the outdoors, rules and manner become more relaxed. Elizabeth becomes more free and expressive. Whereas the action that takes place indoors, it is always formal and follows strict rules of etiquette.
