Statistically speaking, intraverts are pretty rare in our society. I'm fairly lucky, in that I grew up around one (my Dad) and live with another (my partner) and I therefore do have the actual experience of the way they think, and the way they sometimes don't seem to be living in the same reality as I am. It gives them different strengths to my own, and it means they're going to cope well with situations which crack me (and vice versa - I'll cope better with some situations which would send the two of them into shrieking fits). The more typical pattern is that of the extravert, receiving their validation from the external world, and needing that external world to correspond with their internal reality.
That said, I don't think many people bother to turn the story around and look at it from Tifa's point of view. I know for me that was the major turning point - when I suddenly realised how little actual verification of Tifa's story was involved, and how connected with people she seemed to be. I put myself (as an extravert) into her position, and realised if I were in the same situation, I'd be breaking down all over the place. I'd also be struggling hard to keep the mask of normality intact, but inside there's just this shrieking mess. Tifa seems fine despite all this, but that's mainly because she has a few more social skills than Cloud does (or than I do, come to that).
