How I got out traded by a 10 year old girl

Halloween at our house this year was a bust.  It rained.  There were very few trick-or-treaters.  So we were in an oversupply situation when it came to candy going into early and mid-November.   One day,  after a particularly tough day of trading,  I decided to step outside and work in my yard.  The neighborhood kids were out playing.  I thought it would be nice to hand out treats.  I grabbed our excess candy and headed out to join the melee of free play.

Offering up a wide selection,  I told each child they could have one item.  One 10 year old girl didn't hesitate and chose the largest of the candy bars.  But,  after considering her choice,  she returned about 2 minutes later and asked if she could trade.  Curious,  I ask why.  She explained that her dad really liked M&Ms,  so she'd like to trade her candy bar for the M&Ms.  Wow,  I was thinking,  here's a daughter who really loves her father.  She's willing to give her candy to her father while all the other kids were munching out.

Obviously,  I allowed her to exchange her candy.   But while I was in the midst of letting her know she could keep her candy bar and also take some M&Ms,  she deposited the candy bar in the basket,  grabbed the M&Ms,  and sprinted for her front door.  I was feeling guilty that she left so quickly.

Two minutes later,  a smiling girl appears at the front door,  waving $2 in her hand.  "See,  I told you my dad loves M&Ms.  I got $2 for them".

Not only did I wind up losing a bundle of money in my accounts on the day,  I also got out traded by a 10 year old on the playground.   But, watch out Harvard Business School.  I know a young capitalist primed and ready to graduate in the HBS Class of 2027.
