Being self aware, I've know for sometime that I'm an introvert, however this post explains to my satisfaction why I find people's mundane chatter so trying and tiring. I regret that I do not know Apprentice Gerald as well as I'd like to know him, but I do allow him to contribute to the website and that speaks volumes for those that understand.
I've assumed the world is evenly divided between introverts and extroverts and there would be appropriately the same number of introverts to extroverts as there are men to woman. Future research will be needed to confirm this assumption and an enterprising researcher may find, on one hand, a correlation between introverts and the earth and water signs and, on the other hand, a correlation between extroverts and the fire and air signs.
