Regardless of details that come out in this incident this is a real tragedy that will haunt the parents for the rest of their lives. While we all recognize the need to learn from accidents, please try to be sensitive to the family who has just lost their child.
Nothing in the world is more yielding and gentle than water. Yet it has no equal for conquering the resistant and tough. The flexible can overcome the unbending; the soft can overcome the hard. - Lao Tse
