I felt kind of weird going to my first sorority alumnae association meeting because I knew absolutely no one. Then I figured that most of the people were in the same boat and probably didn't know each other before they attended the first meeting. I decided that I would go and check it out and enjoy myself. If I didn't like it, I didn't have to return. I had fun and met some nice people so now they can't get rid of me.
I guess my advice is that you should decide to have fun and enjoy yourself. Be friendly and approachable. Talk to some of the people you don't know yet. You might make some new friends.
