Every person on this planet has some common features like an eye, a nose, a mouth and a pair of ears yet we all have a unique face to distinct ourselves. There are millions and billions of people and yet the almighty God managed to create indefinite combinations with just these few parts. Then isnt it a stupid idea to expect one person to be same as any other person, despite so many variables that can change a personality. We all are meant to be unique in our own ways.
