I call it "situational useless information". I'll walk into a diner with my friends - "Want to hear the history of the diner?" Someone will buy a Pepsi - "Want to hear the history of Pepsi?" Someone will be eating cornflakes - "Want to hear the history of cornflakes?" And so on. 😛
Tell me, have they ever tried to use a topic they think you don't know about and been royally po'd when you did? 😛 People try that all the time on me. 😛
Oh yeah. That brings such immense satisfaction. I love just cutting them off like that and watching their faces as they realize yes, I DO know about that.
