I can be home alone all week and still dread going out to a party if I’m not in the mood. I’m a very social person, but it is still draining. I have never felt so alone that I need social interaction, but I have frequently felt a strong need to be alone.
But I’m also like the parent in that I’ve lead large teams, had greater interpersonal relationships, and have been hoisted to leadership positions regardless of if I was trying to get there or not.
Finally, I imagine the reality of extrovert vs introvert is similar to the modern understanding of gender as a spectrum. I would guess there are not many people that are wholly introverted or extroverted.
