I'm seriously reminded of a bunch of pre-teenage girls gossiping about... uh, what do teenage girls gossip about? Celebrities? Shit that has no relevance to them, anyways.
People are leaving for their own reasons. I have no idea why you lot want to know every little detail, as if it actually has any importance to what you are doing. Are you so self-centered that you think you can change something about it if you know everything about what is happening?
Sorry, you can't. The details have no relevance for you. The results do.
So, yeah, move on.
Or not. It's pretty funny to watch you all running around and coming up with conspiracy theories. (It also provides plenty of opportunities for me to compare you to a bunch of schoolgirls.)
