I'll concur that BR is pretty quiet in RL, but I think that's more from being all agog at whatever Tanith Belbin was not wearing than any kind of introvertedness.
And she talked to me! Of course, it could also be that I am one of the few extroverted people on this board and could talk the bricks off the walls if I had
RockTheTassel--those traits definitely describe my younger brother and me, only in reverse.
It's interesting--I can be defined as both an oldest, middle, and only child. My older brother and sister are 18 and 16 years older than me respectively, and my younger brother is six years younger. I've read that if there is more than five years difference between siblings, the conventional wisdom regarding oldest/youngest "resets." Personally, I like the age difference. My younger brother and I are much closer than we are to the older ones, and despite the closeness in age, closer to each other than the older ones are for each other. If you're going to have multiple children, five years is a good spread. The oldest one gets plenty of parent time/attention on his own before going off to kindergarten, and again, just personal experience, there's less jealousy. Also, you're not at school at the same time except elementary school, and possibly college (grad school where my brother was an undergrad).
