This is SO true:
Extroverts are easy for introverts to understand, because extroverts spend so much of their time working out who they are in voluble, and frequently inescapable, interaction with other people. They are as inscrutable as puppy dogs. But the street does not run both ways. Extroverts have little or no grasp of introversion. They assume that company, especially their own, is always welcome. They cannot imagine why someone would need to be alone; indeed, they often take umbrage at the suggestion. As often as I have tried to explain the matter to extroverts, I have never sensed that any of them really understood. They listen for a moment and then go back to barking and yipping.
The worst of it is that extroverts have no idea of the torment they put us through. Sometimes, as we gasp for air amid the fog of their 98-percent-content-free talk, we wonder if extroverts even bother to listen to themselves. Still, we endure stoically, because the etiquette books—written, no doubt, by extroverts—regard declining to banter as rude and gaps in conversation as awkward. We can only dream that someday, when our condition is more widely understood, when perhaps an Introverts’ Rights movement has blossomed and borne fruit, it will not be impolite to say “I’m an introvert. You are a wonderful person and I like you. But now please shush.”
Surprisingly, I find that when talking to other introverts I don’t get that “on stage” feeling I get when dealing with extroverts. Maybe it’s not that introverts find all people draining, just the extroverts.
