I know what you mean Flora, and I know that you are not suggesting all "sensing" types talk about is biscuits and car parks. Just that the ones you know, or are closest to, often don't talk with the same idealism you hold.
I oftentimes think intuition types talk about things that sometimes bore me too. In the same way, I probably bore a lot of people because I don't talk about what's "cool" or trending, I don't talk about cultural icons and what's happening and I don't talk about other people.
My mum is an esfj and my father is an istp. And I love observing her in the evenings talk to my father about her whole day at work. She will talk for about 40 minutes and my father will give feedback. How anyone can give a detailed account of their whole day, just amazes me. I forget half the things I do, and moreover can't talk about doing things for more than a sentence. My answer when someone asks me how my day was, is "good" *silence*.
Personally, I find the information sensing types talk about, is the missing piece in my life. I need to be around people who are grounded, especially now when I'm progressing as a person. Drawing focus to "what is" (or "what was") allows me to breathe. Allows me to be more objective and reach into Te.
If you get bored, embrace it. Embrace the moment and what they are talking about. Let your Ne find possibilities, but don't fly too far away. If you're game, keep running your ideas past them. It's seriously the best way to look at a subject from multiple points of view other than your own, even if they immediately shut it down. Ask why and how they think what they do. Then attempt to convince them. Engage in a dialogue and learn to speak the different personalities languages. Adapt your communication style. Both you and them have the opportunity to grow (especially because you can get to the root of their opinion through empathy), AND often times, once it's familiar to them and you, it starts becoming more comfortable to talk about.
A lot of istps' I know have some kind of philosophical worldview. There's a lot swimming around in their minds, and they can talk about various subjects when prompted. Estps' are the same from my experience. But again, the romantic fervor or passionate idealism you wont find with all people. I think that's more an Fi+Ne thing. What you might find is a willingness to participate in dialogue about ideas and systems. If that's what they are interested in. Fi is a bit of a hill to get over as well, because good luck trying to get an infp to engage in something they don't like :laughing:
I know plenty of sensors who will talk about ideas. In fact, I really have no problem talking to them. What you probably take issue with is the lack of Fi-ness. You'd probably prefer a little subjectivity. More attachment to the subject than cold objectivity.
Someone has mentioned it before, but infps' feel through intuition, and think through sensing. So as we get older, we're more likely to resemble xstjs' and get along with them. I find that I generally appreciate my time more with ST's than SF's. But I get on with both similarly.
It's funny, I was around esfps' constantly for about 9 years, and they were the ones to really encourage my Ne :laughing:
