If you have children, teach them what I call the “Beaver Cleaver’s Dad Rule.” On the old sitcom Leave it to Beaver, Beaver’s dad, Ward Cleaver, had an office in their home.
The kids knew to only go in there when invited – and if they were invited it was usually because they were in trouble. The kids need to learn that all of the cool stuff in their parents’ office is not for their latest school project.
