I actually don't like to talk, but I have a neurologic problem that causes compulsive communication, both typing and physical talking. I have dyslexia-like problems -- mainly unconsciously switching letters, syllables, word parts. Numbers, especially, I'm terrible at.
I belong to Coyote so I'm a lot like him socially -- I'm happy in a pack, but only if I can escape and get a lot of alone time whenever I need to, which is most of the time. Frankly, that's the place you're farthest off... if you go by this definition of a loner, I'm a textbook example:
"A loner is someone who's alone even in a crowd of friendly faces."
