"So tell me, are you the kind of person who sees a glass as half empty of water or half full?"
"Well, just imagine that I'm holding the glass.........So, would you say it was half empty or half full?"
"An imaginary glass?"
"I don't think that an imaginary glass can hold water."
"Of course the water is imaginary too."
"Imaginary water? Are you nuts?"
"Listen, I just want to know how you would think about the glass of water. You know, whether you're an optimist or a pessimist."
"I would think of it as a glass of water."
"I know, but would you say it was half empty or half full?"
"Why are you bothering me?"
