[Quiet Man Cometh]

Spoon theory!
(not really related save Espy's comment)

On a slightly related note, I happened to do one of those silly "what is your brain like?"quizzes online (Is your brain more Star Wars or Star Trek?, specifically. It was Star Wars) and in the little blurb analysis it was claimed that while I consider myself an introvert, I actually get most enjoyment out of extroverted tendencies, like exploring an such, and overall getting a lot of input from my environment.

I do find social interaction to be draining, but I also enjoy going out and about by myself, doing things, etc, and I do find I can get lonely at those times. I'm bookish, but I still like a good roller coaster. ;)
