If you don't want to share I completely understand but what happened the first time around that makes you embarrassed that you are going through rush again?
I wouldn't worry. Yes, you will probably be recognized and yes you will recognize some of the actives but remember they are different houses now than last fall. They now have all their fall 04 and spring 05 new members and then the girls who graduated in Dec. and May are gone.
I'm sure everything will work out and it will run smoothly
