Recently there has been a commercial with a little boy who slips on a baseball glove, goes out in the yard, throws the ball - but there is no one to catch the ball or throw it back to him. The father killed by a drunk driver.
I once worked for a VP of a large drug company. On his desk was a baseball. If you asked him why the ball was there, he would tell you. It belonged to his son who died at 8 years of age from a sudden onset of a child's disease. He regretted the many times he could not play ball with his son and stated that family time is critical and precious. Then he would ask you; "What are you doing with your family today?"
