Former PG kid from small, Appalachian town, here. My social life exploded when I got to college (sorority vice president, etc.), but middle and high school were miserable! I've lived long enough for the president of my high school class to say, a bit apologetically, that I didn't get as good an education as he got because I was excluded from certain social circles. He once told me, "We all liked you well enough. We just didn't understand what you were saying half the time!"
The extremes in my social life contributed to my underachievement in middle school, high school, and college. Not the only factor, of course.
