Ha! This is an are poorly understood. Because it depends on your definition of Introvert and Extrovert. Let me give you an example:

Some folks think an Introvert is someone shy. An Extrovert then is someone gregarious. Here is a different definition:

An Introvert is someone who is guarded about their internal thoughts and emotions. An Extrovert is someone who "wears their heart on their sleeves," visible to anyone listening.

Using the second definition, I am a gregarious Introvert. I enter a room full of people like a kid in a candy store. Fully at ease walking up to a table and chatting....or addressing the full group. But I'm not going to bare my soul to them. That's done in private, and only to people I trust.
