I really don't want to rag on the genuine concerns of posters here whom I respect, but I'll just say this for myself: I really do like people.
Irl, I can and do get along with just about everyone. For me, this is effortless. I know at least something about a wide range of topics, and can always find ways to engage others. Again, I have to stress, this is not WORK for me. It comes easily and naturally, something I realize is not the case for a lot you folks here.
I avoid politics, of course, and never, ever take the bait if someone else doesn't. I have my views, my values, but I don't ever feel the need to impose them on strangers (except in the thunderdome of P&N!) That never goes anywhere good, and no one's mind gets changed during what almost always ends up as a heated, red-faced exchange with guys shouting past each other.
Other than that, I am genuinely curious about what makes other people tick. I can get just about anyone talking, and in depth, and again, again, again, this happens with no undue effort or burden on my part.
One might say I'm sort of an on-the-ground cultural anthropologist. That, and having little real life fear, is probably what made me a really good P.I.
I bring my sense of fun and adventure to any event I attend, and can always manage to have an effortlessly decent time.
