I love and need my alone time and to get away from people to be by myself, and when people don't respect my personal space and my privacy, I get highly irritated and annoyed on the inside. I get really exhausted after too much interaction/time spent with with others too, when there hasn't been an opportunity to get away from time to time. But on the other hand, if this style would become my way of living, being a hermit living alone in his cave, I would be utterly miserable. I still crave and need some amount of interaction/ inclusion with others and the outer world, I really don't want to be completely cut off from that.
If I had to choose between "being forever together with or surrounded by people" and "living forever alone as hermit cut off from everyone", I would choose the first (allthough it would depend on who these people were, of course), it would be a nasty option though.
As I said, if I don't see or if I'm not involved with people to some extent at least, it eventually drives me insane.
