I don't understand this. Do you mean it literally, people talking about what's going on around them. I have never seen this.
i don't think IEE meant that quite so literally. say we're talking politics. a typical S would talk about individual politicians and how they don't like some of them. a strong N would talk about the themes behind politics such as left vs right or the nature of democracy. of course, N's and S's would likely touch on both ends of the spectrum but you will still talk about one more. i can see how some of the ENFP's here will withdraw given the nature of some discussions.
personally though, i'l talk anyways

. i'm quite liberal like that, i'll talk about whatever you want to talk about (unless we're in class and getting supremely off topic). the times i will withdraw are when there's quite a few people talking about specifics i am not well versed in. say they talk about the relationship between the US and russia, honestly, i don't know my history that well. then i will stay quiet. i won't feel comfortable doing it, but i will.
i also don't think i am as socially active as other E's. don't get me wrong, i have lots of friends that i can talk t and i'm not shy. it's just that my P makes me too lazy to get involved in too many activities. i may like parties but sometimes i just can't be fucked leaving home. my P out-trumps my E i guess in those situations.
hmmm... what else? i used to be quite shy as a child. i was always afraid of saying the socially unacceptable thing. there would be times where i force myself to be more social but end up overacting a role or character i have in my mind. that just creates more social awkwardness. i'm very open now, but yeah, i have definitely changed.
