I recall in a previous life as a delivery dispatcher that someone remarked to me the world would be a better place if everyone was introverted. Immediately the picture of Futurama's Neutral Planet (Season 2, Episode 6) popped into my head, where the Neutrals are about to die from an incoming out of control Planet Express Ship... Neutral Official: Your Neutralness, it's a beige alert. Neutral Leader: If I don't survive, tell my wife: Hello. I know that isn't exactly "introversion", but the point is that only one of anything is usually silly. It would also be horrible for any introvert to be thanked daily for being an introvert, so let's just call that hyperbole before you all point that out to me.
