Wannabes??

Why does some people have to be such a wannabe? Okay.. I have a friend(lets call her Mariah) and she have a friend(lets call her Audrey). I was going to have a little meeting with my friends(just my closest friends) in my house. Well, i dont know how this girl, Audrey, found out about that and told everyone she was coming to my house that day. I figured she knew about my "only closest friends" politic and didnt come.. Well the same girl tells Mariah to invite me to a mall with them.. Only because she want people to know i was with them in a trip! Okay, i dont know if im being such an ass.. but i want to know your opinion people:)
