Realistically, an introvert in the pure sense of the word, in that I don't mind socializing or any of that but it is definitely draining on some level and I feel my natural state is when I'm not around people. I think most people on here will fit in this category, but a lot of people imagine these things as purely superficial. Like, you can have an introvert who is the life of the party, or conversely you can have an extrovert who is socially cut off. It's all about which situation - a social event or a day alone - sounds more draining.
