Yes that's what lives pretty strong in that generation - and on social media in general, I have the impression. For some that goes really far, maybe too far, and people become unhappy or even depressed if they are not seen/approved by others.
Which is like in real life, but also at the same time not quite: in real life conversations etc you show a lot of yourself because it's impossible to hide. Facial expressions, body language, meeting pople early in the morning when you're not at your best, on one of those days where the whole world is against you, and so on. In virtual life however you try to make sure that side of you doesn't show. You could call it a lie. I'm not sure if that is good, bad or neither.
