Don't be different for that reason either. Just be yourself and you will meet others like you. Be proud of your school. Regardless of how you feel about the school, Emory is a great institution. People know it.
Grad schools know it.
Don't let your friends at the City University of New York or the University of Florida get on your case about how preppy Emory is or how much you're paying for your education. You're not paying for the preppiness. You're paying for your schooling. And I'm not talking Dave Matthews here. Go find the organizations that reflect your interests.
