Kel's a 70% introvert...

Reading up the meaning of introversion on Wikipedia:
Introversion is "the state of or tendency toward being wholly or predominantly concerned with and interested in one's own mental life". Introverts tend to be more reserved and less assertive in social situations. They often take pleasure in solitary activities such as reading, writing, drawing, and using computers. The archetypal artist, writer, sculptor, composer, and inventor are all highly introverted. An introvert is likely to enjoy time spent alone and find less reward in time spent with large groups of people, though they tend to enjoy interactions with close friends. They prefer to concentrate on a single activity at a time and like to observe situations before they participate. Introverts are easily overwhelmed by too much stimulation from social gatherings and engagement. They are more analytical before speaking. Introversion is not the same as shyness. Introverts choose solitary over social activities by preference, whereas shy people avoid social encounters out of fear.

Seems like I fit the bill entirely. Did this self-measurement thingy too; Kel's a 70% introvert~!
