My mom was the first person to type me. She did it with one sentence, which was, "Honey, you have enormous empathetic ability, compassionate, kind, and you love to help people."
LOL I guess that would make me an empath in MBTI
It's easy to tell that I see possibilities and potentials in human beings, and I value individual nature of human kind no matter how catagorical the Socionics or MBTI typing is like.
I became interested in Socionics five years ago and learned to VI from Dr. Volkov (a) LOL; one of the writers in the socionics website. I love her she's very nice.
LSE's, like you said, are very active and productive and usually wouldn't waste their time on an internet forum, but it's nice when you do. It's nice when you can give time to your introverted dual, who usually stay in and write on a forum.
