Abby,
Don't worry, you're not the only one who has had a hard time talking to people at the parties. I started out dreading Rush because I had to initiate conversations,keep them going, and I just pray that I didn't ruin it. But honestly, the thing that helped me was the fact that this girl might potentially be my sister-daughter so it might be important for me to find out what kind of vibe I got from her. Not to mention, making them laugh is a surefire way to make you and your rushee relax and have fun (just a one-liner comment works).
I can tell you that Rush is a positive experience in two ways: you choose the very best women to be a part of AGD and the people/communication/networking skills you pick up will help you so much in your career after graduation.
Push yourself beyond your comfort zone and I
promise it'll get easier.
LIEP.
Amy
