Some people think they can act to be strong but they fail miserably sometimes when something occurs from the middle of nowhere.
In real or when she is alone she is a person who is shattered from some incidents occur in her life. She is burden with responsibilities at a very tender age and taught to be strong.
Sometimes when she couldn't hold more and she couldn't handle this dual personalities and sometimes she let go bonds surrounding her and cry her heart out in order to calm down. Sometimes she do this in public and hate herself for this.
She is among us, struggling with her personalities and not blowing off the cover of her hidden personality to get fake sympathy of people. She feel good alone than to be with people.
It happens a lot now a days. People feel alone, and then create another personalities to be around people and grew their friend circle. We should accept the people the way they are. No matter if they are shy or not.
