Last year, two crazy men somewhere in China decided to attack kindergartens and harm some children. Since these incidents, I have noticed that security has really been raised at all kindergartens. As soon as the incidents occurred, many kindergartens had guards sitting at entrances and metal gates erected. So the incidents were a real boon for the security industry.
Last night, Tony's kindergarten issued all parents with name cards that could be worn around the neck. They were issued for some security reason surely.
