Mano y mano

I heard a very interesting conversation coming from the backseat on the way home from school this afternoon.  It went something like this:

E (with right hand in air):  Stop it!

E (with left hand in air):  No!

E (with right hand in air):  You need to share.

E (with left hand in air):  It's my plane.

E (with right hand in air):  I want a turn.

E:  Mommy, my hands aren't sharing the airplane.
