I remember the first time that I heard about extroverts. The particulars about where I heard it don’t matter, so much as I went to my father to ask about this strange word. Note that I was 10 at the time, and oblivious to my status as an introvert.
When my dad explained they were people who ‘had the need to do things around other people,’ this caused my youthful mind to ponder the status of that subset of humanity. “What a horrible mental disorder.” I was forced conclude.
A decade later and I don’t neccessarily disagree with my younger self.
