I'll go so far as to highlight and quote salient passages:
"many actors, I've read, are introverts, and many introverts, when socializing, feel like actors"
"The only thing a true introvert dislikes more than talking about himself is repeating himself."
"I'm an introvert. You are a wonderful person and I like you. But now please shush."
"Second, when you see an introvert lost in thought, don't say 'What's the matter?' or 'Are you all right?' Third, don't say anything else, either." (or ask "Whatcha thinkin'?")
You can read the rest for yourselves.
