I sometimes wonder if I am just an introverted NT. My dad, in particular, used to tell me "Don't be a hermit!" when I was in HS. I really like being alone, much more than going out, and I like to live inside my own head.
Most of my close friends are introverted NTs. We get along pretty well, so I never really thought much of myself being different from them. But I seem to have more issues with relationships, clumsiness, sensory things than my introverted NT friends...
