Shoshana finds it difficult to believe that I'm an Introvert -- which is understandable, since she experiences me in social situations in which I feel comfortable, and I don't do a whole lot of hiding out period.
But for all that I'm secretly an Extrovert (various MBTI books
talk about Extroverts wanting to e.g. process things out loud), I'm currently underslept and after all-day forum, I opted to sit in the lounge with my laptop rather than go to Young Adult Meet & Greet or Bisexuality Affinity Group. Last night I opted not to go out with any of the various groups of people (opting rather to stay in the house on my laptop and sometimes drift into kitchen conversation) but I felt fine when I got up this morning. I'm frequently shy, quiet, and misanthropic, but the fact that when I'm feeling run-down my instinct is to retreat is what says to me that I'm an Introvert.
