Gatsby´s "twin"

I had been thinking in Gatsby´s characteristics and trying to relate it with another guy, but it is really hard.
This problem lasted until I thought about a lady in my previous neighborhood. She seem to be nice, sweet and pretty, full of friends and loved by everyone; eventhough, when you saw all those great characteristics about her, you knew that she couldn´t be so amazing and perfect.

When I grew a little bit more, I understood that she had kind of complex business by her dad´s side because her father always had big black cars and boyguards, o at least that was the image that her whole family and close people gave.
