I've always done whatever I want and always been exactly who I am.
In the public eye, girls and women with strong perspectives are hated. If you're a girl with an opinion, people just hate you. There are still people who are afraid of successful women, and that's so lame.
I hate smiling. It makes me feel weak and powerless and small. I've always been like that; I don't smile in any pictures.
Me and my brother get along super well. We're, like, best friends. So we'll stay up until, like, five just talking because we get along and, you know, it's cool. And he respects my opinions, and I respect his, even if we don't have the same opinions, but a lot of the time we do.
In real life, I'm a really smiley person. I smile when I talk and I laugh.
