That is only one aspect of introversion. Another, equally strong, is that interacting with other people is tiring. A portion is due to chit-chat sociability but a major portion is processing what other people say and formulating the response before speaking. Extroverts get energy from interaction and speak to know what they are thinking.

(That’s not a slam. I’m an introvert, and my wife is a flaming extrovert. That’s exactly how we interact. She sometimes says to people, “Wait, Rud’s getting ready to say something.)

Introverts have problems with meetings. By the time we’ve formulated our response, the extroverts have run away with the decision.
