I believe that thinking that people have three faces is better accurate. Each of us is behaving differently in different circumstances. That happens depending on the conditions on our mood or on what we had for breakfast. So basically your article is one hundred percent right. I would not be surprised if there are even more faces that each of us have such as in between the ones that have been listed here.
Yeah, I think there is room for more but these are the major ones. Thanks for the kind words :)
