Well, learning acceptance is always good. But I know that I tend not to like people who value actions over words. I just don't trust them, because that seems crude to me. Perhaps I'm just not big enough to accept SPs. In fact, I sometimes use "Kinesthetically Intelligent" as a nice way of saying "stupid."It's more that his bad spelling used to really bother me a lot (and still does a little), but then I learned that ISTPs don't value words like we do. As you probably know, they think that actions speak louder than words, to a large degree. So, because he is a valued friend who has given me a new perspective on my art, I accept him for who he is, including his bad spelling, and sometimes erratic responses to my e-mails. I guess that is all any of us really want... to be loved and accepted for who we are.
I'm glad for you that you found it in yourself to accept them, though. I think in words to such a degree that their way of seeing reality feels like a personal affront to me.
