Exactly this. I am a very social person when among people, but pay a price for it afterwards, as I’m drained of energy.

Introverts gains energy by being by them selves. Extroverts needs to be with other persons to gain energy,

That said, most people are not neccessarily completely one or the other.

I understand where the misconception comes from though. Seems likely that being introvert often leads to not be very social since you’re “punished” for it by your own mind.
