I\'m excited!!!!

I have a job interview tomorow. Yes me, a job! I'm so excited yet scared, I havent worked for such a long time, only studied and done very small part time jobs that haven't involved much commitment.It isn't the most amazing job in the world, just a local call center, so local that I can walk from my house within 5 minutes. Pay isn't brilliant but it'll be more than I get now. Its only part time but it's a start right?I have no idea what to wear, they told me smart/casual but exactly how casual or how smart i just don't know.Anyway, I need lots of luck. So if  you have any spare flying about please wish me luck, Im so nervous!!
