What is the law?

Had to give the What is the law speech to my little one yesterday.


He and his little friend from next door had come inside and locked all the doors locking out my wife. And were just having a grand time laughing it up.

When I got home from work had to sit him down and go over the rules
What are the rules?
Is it ok to do that?
Do we play with doors?

on and on.

Reminds me of the Island of Dr. Moreau... What is the law?
