I'm a rather introverted person, I would say. Being in public places and having to socialize, especially with multiple people, is actually physically draining for me. I usually have to spend at least a day alone in order to recuperate, and once I've had my peace and quiet, I fair much better against the outside world. All of this is also coupled with a social anxiety disorder I've had since I was a child, but I've learned to hide it surprisingly well. Most people don't realize that I'm nearly petrified when I first meet them. :eek
But I do okay this way, I guess. I just like my alone-time.
