I think that the majority of people who use Facebook, Twitter, or any other social media frequently hide behind a mask.
Due to their concern for social integration and acceptance. They are aware that, in order to act appropriately in social circumstances, they must adopt a variety of social masks and personalities, even in their daily lives.
I also understand that many people deliberately repress their darker, more sinister aspects in favour of exposing their more socially acceptable ones, because I know that doing otherwise would often be social suicide. The face hidden behind their mask is the one they want the world to see!
Thank you dear friend for leaving a nice comment.
