If you're looking for That Girl Tyson, then you've come to the right and wrong place. Right because this will lead you to her. Wrong because she doesn't really exist anymore.
Don't worry, she's alive, just not in the way you knew her. Still, she blogs, creates and pretends she knows what she's talking about. But she clearly doesn't.
There are many reasons she changed. Mostly she grew out of being That Girl and into a completely different girl.
