Example:
RSI: "So, what do you think of this Prof?"
Hot Chick: "He's O.K. But a bit boring."
RSI: "Yeah, I had this one....(insert story)"
Hot Chick: "No kidding! I had that used to do that too!He used to...(insert similar story)"
(Here RSI is giving his undivided attention)
RSI: "(appropriate response: i.e.; laughter, shock, confusion, etc.) Sometimes it makes you wonder about people."
Hot Chick: "I know what you mean. I had wanted to teach, but I've changed my major to Psychology. I want to know what makes people do the things they do."
RSI: "Really? Like what?"
(Insert extended conversation)
See it can work.
