Why are we limited to EII and IEI? I don't see happening in Uniden's communication, and I think he values .
So if I had to move to a runner-up type, I'd look at Alpha quadra.
But I think EII works. I actually see Uniden as super ethical, both very careful to attend to the feelings of people he feels connected to, and prickly about those he doesn't. He says that he's accepting, and I think that must be true, and I attribute this to him being a really fine human being.
But sometimes when he's talked about people in his life, it's been clear to me that he's been deeply invested in assessing their kindness, generosity, and decency above all, and what distance he wanted to hold them at. He's oriented to making bonds with people and being productive, that is to say, Fi and Te make sense.
(I guess over the years I must have missed out on all the wacky Se aggression, because I've never once seen it.)
I've talked to Uniden quite a bit in the past and pumped out bad, flat for him (as that's what my is like). I sometimes imitated what I thought an LSE would do, speaking aphoristically and telling him problem-solving things to do, at times even step by step.* And encouraging him toward things I think Deltas like, and taking care of himself. It was kind of an experiment, and I hope you don't take that amiss, @uniden. <3 You're all grown up now and I wouldn't do that to you anymore, lol. But my point is, me as pseudo-LSE seemed okay for you.
* This is not what I think SLEs do, because although they give advice, IEIs are full of advice themselves, and their duals probably don't seem to want procedures to follow but to be pushed, even jolted, and cheer-led for their efforts. And maybe to have the SLE just do some of the shit for them, let's face it. With Uniden, I never ever saw him needing to be pushed into action. He's self-managing once there's a plan imo.
