It always amazes me every time I find someone or something on the internet that resonates perfectly with me. I can't stand being alone, it makes me really depressed. But social events don't feel right either, they take a lot of energy as the author says. What I feel best with varies and it's more complicated than just a variation in time.

So what I mean is, he's probably right. Introversion and extroversion are no dichotomy and probably even more complicated than a spectrum. I've heard too many people say I'm an introvert while I feel am not just as this person has heard too many say he's not an introvert.
