You'll notice a blond person is expected to talk. If a blond girl doesn't talk we call her a 'doll'; if a light-haired man is silent he's considered stupid. Yet the world is full of 'dark silent men' and 'languorous brunettes' who haven't a brain in their heads, but somehow are never accused of the dearth.
You know it takes a smart brunette to play a dumb blonde.
Being blonde is definitely a different state of mind. I can't really put my finger on it, but the artifice of being blonde has some incredible sort of sexual connotation. Men really respond to it. I love blonde hair but it really does something different to you. I feel more grounded when I have dark hair, and I feel more ethereal when I have light hair. It's unexplainable. I also feel more Italian when my hair is dark.
