Imagine seeing one of these and believing you're so special that you don't drain other people's social batteries. So you get offended when you learn that you do.
I believe scientific studies say it's somewhere around half of each.
The reason you don't see that, is because it's considered socially unacceptable to get socially drained, so we learn to hide it, usually from very young.
Yeah I was very ready to disagree with it being most people as that is far from my experience. I also come from one of those northern european countries that others describe as cold and closed of because we have a much more introvert aligned culture. And the fact that I’m someone who gets drained probably also biases my sample to more like minded people.
The point is that you don't need to think you're special, or have some unique arrogance to think that you don't drain people's batteries. Younger extroverts have no awareness that there are people who get drained through human interactions.
