LITTLE ROCK, AR. (KRON)—An all-boys Catholic school in Little Rock, Arkansas is drawing nationwide attention after posting a photo on its Facebook page.

The photo shows one strict rule school officials at Catholic High School for Boys want parents and their kids to follow.

It reads: “If you are dropping off your son’s forgotten lunch, books, homework, equipment, etc., please turn around and exit the building. Your son will learn to problem-solve in your absence.”

The principal posted the picture last Wednesday and it has now been shared over 144,000 times, has 69,000 likes, and has over 3,000 comments.

He says the rule has actually been in effect for years, but this is the first time a sign has been posted to remind parents.
