Hmmm..so there are some that identify with it...Perhaps its a Te-Fi thing? Or an enneagram thing? 4's against 7's perhaps?
I do all of the things you've mentionned, but I also like, three times a year have a week, or perhaps two where I avoid all social contact like the plague coz it's just too much effort, spend time in my head and pretty much just have a need to recharge, be on my own. I'll forum a bit (but won't answer pm's as much and read a lot more without parttaking in the threads), I'll put on shows that make me feel good and listen to music that makes me nostalgic, but I'm absolutely not available to *anyone* even my own so at that point.
