poker is so odd.  there i was staring my opponent down, i had a 25$ chip on the table and he was contemplating calling my Q6d bluff.  i completely missed the flop.  fold. fold fold, i was thinking.  my heart was beating in my throat - which reminded me of when i was in cuzco and i had altitude sickness.  oh the pain.  then i realized.  it's not 25$.  it's 25soles.  or 4$ and change.  eff it.  i don't care if he calls.  frick, i prolly lost (or gained) that much in the stock market today and i don't even know! 
but somehow, for some reason, emotion trumps reason.  i care.  i don't care that it's 4$ or 25soles.  it's ego.  it's IQ points.  if he wins, he's either luckier than me or smarter than me.  or worse, he's both.  if he wins, everyone at the table, including dad, thinks he's better than me - at least for the moment.
he folds. 
i try not to crack a smile.  i act as if i knew it all a long and methodically collect my chips.  "thanks a-hole!  better luck next time!" that's what the upturned corners of my mouth tell him.
