My cover has been blown!

[hamms2]

My friends constantly talked about greek life and they always asked me if I was interested and I would said "No". My school recently had an informational that I attended and it was held in a very public place on campus. The night that I attended the meeting, several of my friends and family saw me going to the meeting and now everyone knows that I'm interested in Alpha Kappa Alpha Sorority, Inc. And now my interest in this organization is always the topic of conversation and I don't want everyone to know. My question is: how do i let them know that I don't want to talk about my interest-without being rude? The reason that I am starting to get angry is because my brother said to an AKA at my school, "My sister is GOING to be an AKA." Does anyone think that this will hurt my chances even though I EXCEED the minumum requirements?
