JustHey,
All I can suggest is to listen to your heart and to your mind and let them both lead you to where you feel is best for you, now and for a lifetime. It's good that you are trying to do all that you can to keep an open mind. It sounds like everyone will truly be happy for you regardless of what you decide (I know I'll be thrilled for you, the thought you're putting into your choices so far will benefit you well in whichever group you do pledge!) Please, make the choices that are best for
you.
There's nothing wrong with already knowing chapter members or about a sorority on campus and there's nothing wrong with wanting to get to know as much as possible about all the sororities. Sure, of course I'm biased
The very best of luck when you get your invitations today, because it sounds like you visited three great sororities yesterday. Have a wonderful time at your parties, wherever go you!
Christin
