I am an introvert at heart, albeit my occupation demands that I have constant interaction for an extended period with a small, select group of individuals. This is tolerable because I can adapt and become comfortable with the majority of my cohorts, but this comes with the downside that between the time, the tasks themselves and the people, it brings out the fact that I truly am the sort who would enjoy interacting on my terms and having the opportunity to fade away and come back as I see fit. I become exhausted by it, despite having not really done much interaction.

The more individuals present, the less familiar and the more activity, the less comfortable I am.

In roleplaying context, this fits the theme of my characters and my general personality; I roleplay because I can be creative, do "mostly" as I will in context, and continue to write and think. Interaction is just a quality of it - more dynamic and natural than linear individual fiction.
