Yes! Someone has finally articulated this really well. I'm more of an introvert than an extrovert and this article so right. There's plenty of quotes I could pick so just go read the article.
"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."
Second, when you see an introvert lost in thought, don't say "What's the matter?" or "Are you all right?"
