Every ILI is different. Overall, I have few, if any, difficulties in getting along with ILIs. I think they are interesting, intelligent, sometimes mysterious, which I like, sometimes a little dry, sometimes a little boring (usually applies to the 'nicer' ILIs, not that I like jerks, but I like those who speak their mind truthfully and don't try too hard to be socially acceptable to the point of squelching their own ego with a persona). Some are extremely clever or else elusive and intriguing. My favorite characters in fiction are always ILIs. I often find them the most fascinating.
But as a rule, I think of ILIs as reserved, intelligent, and very good and very kind people (also the most physically attractive type, especially those with the classic ILI appearance of wearing glasses and having a rather emotionless, withdrawn demeanor, and seeming detached from the physical). I've yet to meet an ILI, irl, who was not a kind person, even if they were grumpy on the outside, which I tend to find endearing. But I often rely on ILIs for their knowledge and patience. I like helping them in physical tasks and in issues requiring diplomacy (I've shielded an ILI supervisor in overwhelming or else difficult customer concerns and queries). I feel a desire to defend an ILI when others go on the offensive merely because they have spoken their mind, often a criticism.
ILIs to me are relaxing to be around. It's easy to talk about anything and to find agreement on many things. I don't feel self-conscious, usually, around them. These are pleasant friendships that are usually built on real trust, affection, and acceptance. I usually can learn a lot from them without being made to feel like a fool. They usually seem to like my groundedness, friendliness, and level-headedness, low-maintenance, and the fact I don't create drama and when drama and tensions arise, I can diffuse it with pragmatism, diplomacy, and humor.
I'd say I am, like other SEEs I know, reasonably intelligent and cultured and educated, if you will, and can interject it here and there without really flaunting it. I can be prone to making errors in logical judgments and can struggle to recall facts that are disconnected from actual experience.
