I don't see much fun in that.
For lack of better alternative. And, they genuinly care. They're true friends, they just simply cannot provide what I need. I can laugh and have fun with them, I cannot have deep intelligent conversations with them. It's all fine as long as you stay aware of what you're talking about to whom. Saying the wrong things near the wrong people causes 'trouble'. I'm not sure how to explain this, but ask on if you wish to know, I've just often felt capable of 'leeching other peoples happiness'. Being happy by being around happy people. Who cares if they're happy sensors, I just need to be near them for the effect.
When hanging out with the type of people you're talking about, I don't usually join conversations I'm not interested in. Instead, I provide comic relief; satirical commentary on their conversations, jokes, even let them laugh at my weirdness. This makes them laugh, and I enjoy it as well. I find it a better solution than "small talk".
I don't really mind smalltalk. It bores me, but i've learnt to go with it, and at times (rarely) even talk about random stuff myself. Obviously the topics are (subtly) diffrent, but it's still fun chatter. If i'm not up for it, I'll change subjects. It's honestly not that hard to change the subject unless they're in some emotional mood and need someone to share their hearts with. (Which rarely happens as I will start logically answering to everything even tho I know I shouldn't...)
I let them laugh at my weirdness, but that's not the only thing we laugh about. I'm honestly not too bad at making random, admittingly sometimes offensive, funny remarks about whatever subject they're talking about, and we'll all laugh. I'll admit, even then, sometimes I'll be silently grinning at jokes i'll never tell in their prescence, cause they wouldn't understand, but is that so bad? Is it inherently diffrent from smalltalk?
When i'm near sensors I basically have an additional filter on what i'm saying. As an introvert, I feel it comes somewhat naturally to think about what i'm saying. When i'm near sensors, i'll be saying diffrent things than when i'm near intuitives. While I'm more interested in the talks with intuitives, laughing about random stuff is the same with both kinds, regardless of the jokes being diffrent.
