Take your two children to a football scrimmage.
Let the oldest one get incredibly sick on the way to the restroom, in the restroom and on the way to the car
and
Let the youngest one vomit all over the baseball field and her shoes as her Mother quickly turns her away from the spectators watching the scrimmage.
I know, you are just beside yourself trying to digest why you didn't think of this first.
We truly are the classiest and most graceful family you will ever, ever meet.
