Sometimes I wonder if the movie and TV show depictions have cemented these impressions. It is an extremely lazy mind that makes such assumptions, Rebecca, for it's true work to see each and every one of us as a unique individual with definitive personality traits. What's drama for some is simpy enthusiasm for others, exuberance for even more. To place judgement on the expression of any individual is to dampen and try to control or corral who they are out of our own fears.
