For the record I don't think Z and Ed have left at all. I don't think that's what they meant (referring to Z's comment) about taking their ball and going home. I think she was just trying to put a humorous spin on her comments.
People are allowed to disagree right? I never thought that either of them were storming off the forum so to speak. Z doesn't post all that much anyways so it isn't really out of character for her to not post again for a bit.
