In high school, there are so many cliques. You're never safe. In between my junior and senior years, I went away to film Sisterhood of the Traveling Pants, and I came back ready to do the things with my friends that we always did, but things change. People get older, and there are some inside jokes that you don't know about that have happened. You feel lost for a while, and it's hard to come back from that. Then the friends who have 'replaced' you are territorial. I've experienced that a little bit. There are catty, insecure, and gossipy girls everywhere, but for me, I don't think it's a matter of any of them being genuinely bad at heart. I just think that maybe the different ways in which people are raised make them different and insecure. They point out the bad things in others just to make themselves feel better. It's everywhere.
