On the one hand I'm exhibiting signs of extroversion. Going out, chatting with new people. Taking charge, talking in front of people. And yet being in crowds doesn't actually 'recharge' my social battery, and I avoid large crowds where I have no function or purpose. So, still an introvert. But I can be extroverted when the occasion calls for it (which seems to be very often these days).
I recently took a Jung Typology test. I was pretty close to the middle on two of them (one of which was slightly on the Introvert side) (~5-10) and notably toward one side of two of them (~10-20). I'm guessing that means I've become a fairly flexible person these days. That or someone will say I can't choose which side of the fence to sit on. :-P
