PLEASE HELP!!!!!!! Friend troubles!!?

Tell Fiona what she does isn't cool and that she needs to stop putting on this act around Zoe cause that's not impressing Zoe. Zoe don't care whether you are friends with me or not. Me and Hannah don't need that fakeness around us. Not to be mean...maybe I do need to be cause you are so being mean to us right now. There is a thing called manners and moral. Just tell her that if she is only going to be friends with you when Zoe is around, then just forget about being friends with me period. Hope that helps. But if you don't wanna be that mean just ask her what her problem is.
