A lot of people you see online seem to run their life like a PR firm these days, talking about "genuine experiences" as so forth.
I think we all perpetuate an imaginary personal narrative which we present to the world in such a way as we think other people can either understand or accept as plausible, until someone or something presents itself in our path that makes us stop and rethink where we are heading, hopefully for the betterment of everyone involved.
Sometimes you are taught the narrative of your life by your family who have established their own story as a group and then on the larger scale you are taught to believe the societal narrative you are expected to follow the norms of. Where your own personal narrative becomes a factor is influenced by how well you can function within these other narratives or how you are perceived by those around you.
So a lot of people’s behavior seems to be based on how they feel they are being treated or are being told to behave by others who have more power or the need to have a cohesive unit to work among.
