John and Robert Kennedy as teenagers were out sailing a small boat when a storm whipped up.
They beached the boat down around the corner from where they lived, tied the boat up and walked to their house.
They walked into the house soaking wet and their father demanded to know what happened and where the boat was.
The father made the boys go back out to the boat and finish sailing it home.
It was a lesson for the boys never to quit something they had set out to do.
