Whoaaaa, Nellie. You are talking to an extrovert, here....LOL. I don't agree that that statement is true across the board. Not from my experience, anyway.
What I was driving at was this: Sometimes, the people in our families (for their own dysfunctional reasons) see us as very different that the whole rest of the world sees us.
From this, we may take some comfort that the people who are berating us may just be grinding their own personal ax for some reason (alcoholism?).
I have known lots of introverts...and, many of them seemed like contented people---just as happy as anyone else.
