Yep, I'm the same way. 'Normal' conversations and small talk are so... boring. I prefer talking about something that will make me think or reconsider the view I have. Something intellectually stimulating. Luckily my INTJ friend is great at coming up with really interesting topics for conversation (and he's a lot more open minded than most other J's I've encountered), and my INFP friend always contributes a different side to to the views that the INTJ and I hold (he and I think very similarly most of the time). It's refreshing after dealing with the people in my classes all week.
