Yep, I expected you to say that about the events and organic relationships instead of contrived ones. We're the same in that way.
I just move on from that person. I will most likely never want to be around them again.
This is a strength in my opinion and I have it too; I'd rather be with no one than someone negative. It makes one's circle smaller but I'm ok with that; quality over quantity.
I'm a confident person, confident in myself, not arrogant, just confident and comfortable in who I am, what I know, how I converse and interact and feel no need to have others confirm it; in fact, when people do I feel it could be disingenuous. Having said that, I'm shy in social situations - not socially awkward - just shy and unwilling to be the centre of attention - happy to fade into the background - which makes doing some of the professional roles I've had a challenge. As I said in another comment on this post, I've played the parts though, worn a suit as a costume, so to speak, so I can act the part or as a suit of armour to make me feel able to do what I need to...So, I'm not sure I agree with your last comments in respect of myself, but I understand the relevance and that that situation is indeed a reality for some.
Edit: Also, I sometimes get the feeling that I'd get along with/connect with people even before I meet them in person...Have you ever had that? I can't define why, it's a feeling more than anything, but sometimes I get it quite strongly.
