burning like matchsticks in the face of the darkness

In recent years I have less and less posited Introvert as a dominant personality characteristic for myself as I have become both more comfortable in social settings and also more outspoken generally. [Plus, knowing some people who are VERY introverted has made me feel VERY extroverted.] I am still more comfortable alone or with small groups of people with whom I am close than I am in large groups, though, and I definitely tend to wait before speaking more than I speak up immediately. And you mentioned "people-oriented" and we know I am (almost) always me-oriented :) So yeah, Introvert still feels more accurate than Extrovert but less accurate than it used to. Which brings us back to my original "Why can't we just use descriptive words and phrases rather than acronyms?" Labels can be useful but also problematic. Because they are basically shorthand, and everyone is complicated.
