Openness-Privacy is a dialectic that describes an individual's desire to communicate openly, while being entitled to a certain degree of privacy on some matters. For instance, in this case, Anna and Greg are seemingly good friends and share a lot of conversations on various subjects; however, Anna dislikes Greg's incessant questions regarding the problems she has with her boyfriend because to Anna this subject falls in a more personal domain and she does not want to disclose private matters with Greg, though they talk a great deal.
Hope this helps!
