Note: For my COMM 327 class, we were asked to bring in a favourite quote about interpersonal communication. Here's my contribution:
"You know," said Arthur, "it's at times like this, when I'm trapped in a Vogon airlock with a man from Betelgeuse, and about to die of asphyxiation in deep space that I really wish I'd listened to what my mother told me when I was young."
"Why, what did she tell you?"
"I don't know, I didn't listen."
-From Hitchhiker's Guide to the Galaxy, by Douglas Adams
