I probably am weird, but I LOVE my alone time. Maybe it's because I was an only child. Learned to entertain myself in my head. I hate crowds, loud parties/activities and do not have many close friends, just a few. Yea - it's the only child syndrome.
I hate to say it, and maybe I am selfish (again, only child) but sometimes I wish I could just go away for a while and do only what I want to do.
