But also there's a distinction...I mean, simple communication and basic interaction is one thing. Chit-chatting, deciding on where to eat out, day-to-day things. I don't think that's an issue. But the type of conversations (topics) and manner of communicating and telling stories (one of many examples - valuing details vs. not valuing details...and no, not all S's value details. Each of the 8 S types would be different in this regard) is another. As for N's saying "S's just don't get IT", it's probably more a difference in the latter - different conversation preferences and different focuses on the subject at hand. An N viewing the subject in one light and placing importance on characteristic A, vs. the S viewing the subject from a different angle and placing importance instead on characteristic B. The N then deems that the S 'doesn't get it' because the S isn't seeing things in the same light as the N, or doesn't place importance on what the N places importance on. Of course you could totally turn it around and the S could be equally justified in being annoyed that the N doesn't place importance on what the S places importance on. haha. But we could do the same thing with E/I, or F/T, or take all of the mbti letters out of this entire topic, as this is basic human psychology too. Everyone being different and focusing on/valuing different things, and unless both parties actively work to communicate and explain themselves in understandable ways, things will get lost in the shuffle.
As for the NF=awesome humanitarian stereotype, I freely admit that's one reason I didn't think I was an NF many years ago -- because I don't consider myself in that light at all.
