There have been many times in my life where I have had
complete conversations with someone and not heard a single word they said
because I was distracted by the conversation going on in my head. Glassy eyes,
a frozen smile or non-committal vocalizations are all clues that you can start
reciting the Gettysburg Address and I would continue to smile and nod like an
idiot while caught in the hypnotic trance of my inner monologue.
