3 faces

3 different faces, that's all we need, that's all we have the right to. Not everybody will have to use them, others take steal them from innocents who can't defend themselves.
One is strong and sharp, rigid and emotionless. We develop it over time which implicates that it's not completely static compared to the length of this period. Exception is the rule, of course, but most will have to work for the hand that nourishes our lives.
One is smooth and ideally maleable, to fulfill its role to feed the heart. There are some who live without a family, they compensate this with their two other faces - for me this is not the way to choose. I could not survive this lack of deepness, warmth and concealment.
The last one and second oldest is the most plastic. It greatly depends upon our social environment because this one belongs to your friends. Ideally they compensate your other lives and aid you to your completeness and to lead a balanced life.
