If anyone is interested, I would highly recommend reading Bret Easton Ellis' first novel, "Less Than Zero". It is like an 80's version of "The Catcher in the Rye". Sooooooooo Moving!!! And it is also why I think the author used to be, or is an INFJ.
I can see an INTJ, but looking at the fact that INFJs can be mistaken for INTJs, I stick with my hypothesis. Of course it is hard to type someone so psychotic.
"Less Than Zero" is good but depressing. I like "The Rules of Attraction" as well.
