Vanity

You're so vain; you probably think this blog post is about you.

Of course if you don't think it's about you, then you probably are not as vain as I thought you were, and that would mean I'm a rather mean person to insinuate that you are so vain.

On the other hand, this blog post is indeed about you, and so for you to think that it is about you is not really all that vain. It would seem like I am the jerk from this perspective as well.

But seriously, you're vain. That's all I'm trying to get at.
