Though, I do take great pains to always ask him what he is thinking and to draw him out on issues, when I am with other N's, it seems like there is this implicit understanding that we are both curious about each other's viewpoint and so if we raise an issue or discussion point, the other naturally contributes their own without having to be prompted and it becomes a natural exchange where both are discussing the other's viewpoints and nobody thinks or feels that they are being pontificated to.
One thing though, is that I do watch for body language signs of boredom or discomfort and navigate around those, and usually make some sort of joke about getting off the soap box or whatever, and move the conversation over to the other person.
But I tend to find a natural rapport with many N's that doesn't involve me or them constantly needing to reiterate for each other that we are interested in each other's thoughts regarding most subjects.
Now I am curious if the other N's on the board find this as well?
Gawd, it's scary how much you sound like my ex
This I think is a flawed perception on your part and it's something my ex did that drove me nuts.
It's not that ISFJs (and probably SJs as a whole to a larger extent) aren't curious about things, it's just that we tend to direct our curiosity toward things of practical value (or maybe that's just me). The only time I start to get into really abstract stuff is when said stuff is directly impacting my life in someway. As EJCC pointed out, it has to be something
useful to us to feel like talking about it. This means that we DO have strong opinions about certain topics but unless we can find some valid reason to bring it up, we may just not feel like we really need to talk about it.
For example, I have a very strong opinion religion. Does this mean I go about talking about it all the time? Not at all, and in fact I barely ever talk about it. Why is that you might ask? I don't talk about it much because I don't
need too. There isn't anyone trying to impress their faith on to me, my rights haven't been suspended because of my beliefs, and by and large the people around can't seem to be bothered to bring the topic up with me so I simply don't really discuss it.
Sensors are a very practical, here-and-now bunch and our thoughts tend to gravitate toward all of that. I do think about other stuff at time but by and large other things consumates thoughts in my head.
For example, by and large today I thought about the following
1) Idiots I had to deal with at work, and why I felt they were wrong
2) How angry I am about my breakup with my ex many months ago, my concern that I'm still brooding over it even after all this time, and pondering the
real reason I still feel so much anger and what I can do with it
3) How I'm going to maintain my protein and caloric intake for the purposes my working out/personal trainer given how goofed up m schedule got today
4) Why I really like Star Trek (I watched an episode of TNG on my lunch break and it brought up a lot of nostalgic feelings. I love being an Si-dom

)
5) Things I want to do when I get home, goals I want to achieve in World of Warcraft over the weekend
6) As a result of this thread, about my ex-g/f and how her and I interacted with one another
See politics/science/religion/philosophy anywhere in there? No and you know why? Because I didn't need it.
I think you might need to realize that he's not going to be the naturally curious thinker that you are. That's not a bad thing, it's just a way that he's different. But I think you're going to need to evaluate how important this is to you in a partner.
