"Privacy is not a static construct. It is not an inherent property of any particular information or setting. It is a process by which people seek to have control over a social situation by managing impressions, information ows, and context."
In other words, privacy is what you make it. There is not a definite definition and it is varies from person to person. I think that everyone perceives privacy differently and that in someways it is a spectrum. While some adults struggle to understand how teens can demand privacy while maintaining a social media presence, it is completely feasible and possible for teens to do so. Privacy isn't synonymous with being off the grid and anti-social and it shouldn't be. I think, especially in the 21st century, there is an expectation that everyone has a social media presence and there still exists the expectation to keep somethings private. It all depends on what each person is comfortable with. Some teens are comfortable with sharing every aspect of their life on a public account while others control their social situations by maintaining a private account that only a select few can see. It all depends on the range in which someone is comfortable with sharing personal information about their lives. For instance, it lately has become a trend that many teens will have "rinstas" or real Instagram accounts where they may share less personal, general posts and "finstas" or fake accounts which usually are private and only followed by close friends. Finstas give teens the opportunity to be more open about their lives and many people use it has a place to post rants and more personal information, all while controlling more specifically who can see what they post.
I personally think that there is this connotation that if you have a social media presence, you must be comfortable sharing anything. That is not the case, I think when posting something online most teens put it through their own personal filter, their own definition of privacy. This filter questions whether something upholds the image they want to maintain and does it give followers a look into their life without revealing too much. This is the modern way that teens interpret privacy and seek more control over the social situations and expectations.
