On my first night of class, I announced to the class that I thought the notion of informal empire was like porn.
I elucidated reasons. Everyone has a different definition for what constitutes one but they know it when they see it, the mere notion of them elicits strong emotions in audiences, and they will exist as long as there is free market capitalism.
But still. For the rest of the semester I will be The Girl Who Compared an Economic Dimension of Foreign Relations to Porn.
