Here's the pathology:
I like people who like people that I like.
I don't like people who like people that I don't like.
I want to like people who like people that I like or don't like people that I don't like.
I don't like myself.
You don't like me.
But since you don't like somebody that I don't like, that makes me want you to like me.
And this hurts that you don't.
