It's more about accepting you inside a circle and openly sharing information before getting to know you than about initiating conversations.
I was on a sort of semi-professional trip, bonding and spending quality time with someone I like. A mutual acquaintance arrived later with a friend (profession call) and unintentionally invaded our private space by imposing his ideas about what would be good to do as a group in our spare time and constantly "entertaining" us with his jokes and stories, regardless of whether we want that or not. My friend (not exactly, but let's call him that for simplicity's sake) had no problem accepting this guy's initiative and delegating equal attention to everyone in the group, while I, on the other hand almost hated the fact I had to tag along and listen to stupid stories (meant to keep our spirits/moods up or whatever) and not being able to have more intimate discussions and less restrained interaction with my friend one-on-one, which is always far more satisfying than shallowly socializing on a larger scale. To make things worse, two other not-so-close acquaintances joined our group later (just like, for no reason at all) and contributed to making the rest of our stay as stifled and superficial as possible. Anyways, the act of "letting whoever barge in and impose their presence on a relation/interaction already developed or in progress" is what bugs me, personally.
There have been other situations bringing up this issue, and I'll write another example if I can think of one, but the main theme behind it all is that there's group A that derives satisfaction in exploring relationship potential with individuals and find value in confined and intimate interactions, and there's group B who either don't care or put secondary importance to inter-personal bonding, focusing on social impact, influencing people, promoting image and/or status, or just being equally nice and accepting to everyone with a lesser or non-existent sense or need for discretion and intimacy. All things aside, the key point in all of this is how much one is accepting and inclusive of outsiders in their personal space and relationships, and whether this kind of inclusiveness is indicative of Fe as a valuing information element or to Te/Fi aristocracy. I have seen it being attributed to both, and while I know how I feel about it, I was wondering what others think.
