I think that you could be correct. I did find that taking that test was not easy to answer some questions. I read an article describing what those people are like. I thought that I could identify with it for myself.

My sister told me that she is that, too. Personally in knowing her, I'm not so sure. As far as the introvert part, I think that she and I are different with that. If I took her to some kind of social gathering, when it's over, I'd have to drag her out of the place to get going because she would talk a lot to others. Also, I prefer to be alone than to be with bad company. She would prefer bad company over being alone if that was her only choice.
