This is sort of an ironic title, given that we introverts aren't exactly the most comfortable in large crowds - even if they are comprised of our fellow introverts!
I came across an article by Jonathan Rauch in The Atlantic called "Caring for Your Introvert" - check it out if you have a moment. It's a little tongue-in-cheek vindication for those of us who are labeled "loners" and cause people to worry simply because we're not as gregarious as other people.
