Shady IG's are everywhere! But I think all serious sisterfriends have experienced that one girl who seems to be everywhere you are and basically stalks you b/c she thinks that you have a good chance of getting in. I had a girl who stalked me & a friend of mine b/c she said they seemed to really like me. That may be the case but that's none of her business

She used to stalk my sister who is now in another sorority, to try & get close to me! Crazy. But don't worry, the members know who is sincere & who is criminally insane or insincere. Just make sure you don't encourage the "shady IG" b/c you don't want death by association! lol
But I think it's wise to just be kind and speak to people, b/c amongst us is where the next line comes from. But you can tell the difference btw a real sisterFRIEND and a shady young lady. I have been friends for about two years with a girl I met form going to programs. So you can form real relationships with girls who are there for the right reasons.
