The best advice I can give is: Don't listen to what your friends say. Instead, listen to what
your heart says.
It sounds as if being Greek is something that you've really been thinking about a great deal. My suggestion is to go through Rush and form your opinions about the sorority women then.
I didn't know much about sororities when I went through Rush either, and I'd definitely heard all the stereotypes from non-Greek friends. But, when I went through Rush and saw all the wonderful things Greek Life had to offer, I realized that it was definitely something for me.
I can't imagine going through college without Delta Zeta. And I can't imagine moving to Atlanta without the support of my DZ alumnae sisters who were already in the area. Wherever I go, DZ is with me. That's something to be proud of.
Good luck in your decision. I strongly encourage you to give sorority life the old college try!
