So what you're saying is we're all just the same people drinking blood, but in what situations we drink the blood is how we're determined on the scale...
Nice metaphor for alcohol, but that's not how introversion/extroversion works, there's many in betweens through these two extremes
@Sivls, I agree. It's more about what drives and motivates you. Introverted doesn't mean anti social. It just means you're more productive and motivated alone, and more drained around people. Vice versa for extroverts. I know anti social extroverts, and that's why they suffer with a lot of mental issues because they don't like being around people, but they need to be.
