I've learned to "fake it" so well that I can seem more social than my wife, who is a very social person. And yet, I'm always aware (on some level) that I'm faking it. Life is funny ;)
It's not easy to talk about. People tend to get defensive.
Most smiles that I see seem forced, for example. And even when I'm eavesdropping. So it's not just about me ;)
But it can be learned. Decades later, I still vividly recall the video sessions at the start and end of the est 6-Day course. Most people managed to own their act.
Because to some degree we are all faking it, but then when does the front become reality?
