Public:  Emma maintains her public appearance during the fair by denying Rodolphe's first attempt to seduce her.  During the fireworks show, Emma stands with Charles and rests her head on his shoulder.  When Rodolphe asks her to go horseback riding, she denies him at first because she is afraid people will talk.  Once Rodolphe thinks that people will see her go into his house, he worries that the affair will be found out.  He tells Emma that he does not want her to compromise herself so she should stop coming over. 

Private:  At the fair, when Emma and Rodolphe are alone, he grabs her hand and she does not withdraw it.  At the firework show, while with Charles, Emma is secretly thinking about Rodolphe and how this might be her chance to engage in a romance.  Rodolphe goes to Emma's house after his return and when they are alone he tells her he loves her.  When they are on the horseback ride together, she gives herself to him because he sweeps her away like the characters in the novels she reads.  Emma sneaks out of her home many times so that they could be alone.
