When I was a whelp in Philadelphia, there was a rash of
kids suffocating
in old refrigerators during a big garbage strike one summer. Hide-and-seek
You can tell kids all you want, but some are still
going to play on the
train tracks, in old refrigerators, in dumpsters...
The only thing is this instance that seems to really work is to fine anyone
the puts out a fridge without removing the door hinges. Children by
definition cannot be expected to obey rules, regardless of the rule.
