and enjoy life as much as possible in a SAFER WAY. There is a difference of being responsible and reckless. The parents should warned their kids the danger of playing on the roads, the kids do not understand that. So unless I think something happens bad (GOD forbids), then they realize how to value life and respect the roads!
The best protection for danger is being cautious. Prevent before it happens.
