She could not help it. The laughter had taken over her being and now she only existed as the uncontrollable exhales. That was all she was; which was far more than she had ever been. A shell or perhaps a mask. Covering up the lack of substance and personality.
It wasn’t her fault; at least not entirely. The world could’ve have been a bit more understanding of her chaotic creativity. But the way it always goes she was branded a lunatic.
At first she’d fight it. Tell people off. Stand up for her beliefs. Eventually she stopped. Her efforts were all for nothing. Realising she would never be seen as anything but, she instead became it. She did not own it; she was consumed. The very essence of her being had abandoned its independence and was now solely an image of what other people saw in her. Their prejudice; most of all their belief that she would never be anything but.
And so it goes. The different become freaks and individuality withers and dies.
