While driving with Chan to his movie date:
Me: Chan- who are you meeting at the movies?
Chan: Tersely- "Someone."
Me: "A girl?"
Chan: "Yes mom, a girl."
Me: "Do I know her?"
Chan: Irritated- "No Mom- you don't"
Me: "Aha...I can tell by the way were lips are pursed that I know her....hmmmm. Is she from ROTC? Does she attend [your highs school]?"Chan: "No Mom, she is not in ROTC...and yes, I go to school with her."
Me: "LIAR- SHE is in ROTC...I can tell ...by the way you exhibited a vocal tremor!
Chan: Quietly shaking his head...well, sort of disgustedly shaking his head....
Me: "Nothing- I just got your truth baseline."
