Nah, Tarnfalk, I don't think you ruined anyone's fun! See, this is why my assessment of my personality makes me go "hmm". As a "mediator", I'm supposed to be unfailing empathetic, to a nigh on psychic degree. But I regularly say/post things that apparently hit other people like a wet blanket. Or cement truck. And I don't say things with ill intent, in these cases. I'm certainly not an angel. I get snarky. Often. But, what I'm talking about is when I think I'm just saying my opinion or setting facts straight, and then I realize I crushed the other person's enjoyment or they think I'm being mean. It's confusing. And as a proper INFP "mediator" I shouldn't have that problem!
I reaaally doubt, given that tendency, and the aforementioned snarkiness, that other people would peg me as an INFP. Introvert, certainly. But maybe not the rest. Or would they, and I just don't see myself that way? All interesting questions, yeah?
Also, the world shapes people. I probably started out more true to my personality "type". I recognize the old me in some things, like thinking that people are always good at heart. Yeah, learned the hard way they aren't. But the same personality type that originally fostered that attitude must still be intact enough to check the INFP boxes for it. So, psychology really is fascinating
