Hmm some of it actually sounds more like me. I'm not a really strong extrovert either though. I actually think we'd get along really well if I wasn't so sensitive to their attitude sometimes.

The one INTp I know is just so jovial in person you can't take his criticisms seriously. He is married to woman who says she is an INTj but I'm not too sure about that. If she wasn't so warped it would be easier to tell.
