I'm Scared

I'm getting my hair cut tomorrow. I know who is going to be cutting it - she's a student at a local hair school who I also work with at Pepsi. She's done other people's hair who we work with and as far as I know it's turned out well... but still, I'm nervous. I'm also nervous because I have no idea what to do. All I know is that my hair looks way better with layers than one length, and also with some very long side swept bangs too. I'm nervous though, just the same.
