Whatever. The point is, is that I don't think you're quitting because you believe these things you say. I think you want to believe them because you're quitting. You want me to agree with you and say, "yeah, you're right. "it's all fucked up. It's a fucking mess. We should all go live in a fucking log cabin." but I won't. I won't say that. I don't agree with you. I do not. I can't.
