That's very interesting.
I agree that we have different personas depending on the situation that we are in or who we are with. We certainly tend to act differently around our co-workers vs our family vs our friends. There is an interesting book about that sort of thing called the self illusion. Its basically a tour through psychological research on identity, memory and overall how our brains function. Basically its overall message is that the "self" is constantly shifting, adapting and changing overtime and to fit the current situation. There is no permanent "self" though we tend to believe that there is.
