Tara, right now ONLY worry about high school. That is so much important than something that is two years away! By the time you are a college freshman you will be a very different person than you are today. Trust me!
When you do get to college and rush, the sorority that you fit best in will be the one that you're most comfortable w/ during rush.
To be in a hurry to grow up. In a few years you'll be wishing you were still in high school.
