hmm... just thinking of the two INTJ's I know personally - they don't really seem to try seriously to have conversations about things that are important to them, so most of what I talk about with them, they're cool to laugh about and they can take people poking fun at them.
INTP's yeah, easy going... up until you hit a nerve by accident - usually by saying something which touches on some deeply held opinion of theirs on their pet subject. I know one INTP, a geologist - he REALLY likes rocks. A group of friends were talking about beaches, deciding which one to go to (there are quite a few locally, it's an island!). One guy said he liked the kind of sand you got at a certain beach, then the INTP who had been quiet until then, suddenly jumped in and started arguing that what this guy was talking about couldn't possibly be actual sand, by the geological definition of sand, and everyone was like dude, look, the word "sand" was invented for that crumbly powdery stuff you get at the beach LONG before geologists started categorizing things, can you just chill and let us call it sand, cos that's what it is to us? But this INTP wouldn't give in and really pissed everyone off with trying to get us all to admit that, by the proper geological definition, this guy had been wrong and the INTP was right. Eventually he shut up but he sulked the rest of the day and still holds a grudge against that guy and calls him an idiot.
That got him the nickname of Sand Man, and since he rarely talks unless the subject of geology comes up, he's made an image of himself as an uptight twat who doesn't really care about anything except geology. Whether that's true or not is a moot point - it's how he's portrayed himself. Yet he blames other people all the time for him not being able to get on with people.
