I adore Russian and Australian accents.
Russian accents are totally sexy. The language itself has a lot of texture, it will roll and dip and then crash down on you like a gigantic wave. I hear a Russian accent and I want to say, "Take me I'm yours!" But I do not. I am a lady.
Australian...
I tend to use the fancy words whenever I'm trying to be serious, otherwise I speak very casually. People tend to give me funny looks otherwise. That makes it awkward. So awkward.
