I have a friend who, by my best guess, is ESFJ 7w6 sx/so, pretty much my polar opposite. At first, I wasn't sure we could really get along because I felt really awkward and uncomfortable around her. It kind of seemed like she would speak at me rather than to me, which made it really hard for me to contribute anything and hold conversations with her. But then I discovered that if I talk to her in Si, we're speaking the same language. It takes a bit of effort, but when I do that we can have a lot of fun. I also think her sx instinct helps, because I have a much easier time one-on-one than in groups.
