The other Friday night my family gathered around the dinner table to play Texas Hold-em. My 10 year old son arrived at the table wearning sun glasses.
He need not have bothered. He has a tell.
Whenever he gets a good hand, he pumps his fist and whispers "yes!"
Whenever he gets a bad hand, he rolls his head back and hisses "oh man!"
I think my wife drums her fingers when she's bluffing, but we didn't play enough hands for me to test my theory.
The scary thing is that I couldn't tell my daughter's tell. This may prove problematic as she gets older.
I have no idea what my tell is. But I'm bound to have one.
