I am both an introvert and an extrovert. I don’t think this is so unusual. We probably all have intro and extro versions of ourselves. It’s kind of like masculinity and femininity but with less chance of offending everyone.
The issue for me is that my Intro and Extro are constantly fighting.
My extrovert is constantly inserting himself into social situations in a chronically desperate scramble to be seen, and my introvert is mercilessly judging him for it.
Especially in the middle of the night.
