This tradition is often used in the developing world, and is common to be around 7:30 in the afternoon so that the children can get enough sleep and not be tired for the next day.
A child who refuses to go to bed may be tortured as much as possible or to death, as long as he/she goes to bed, according to one of the law's rules. If the kid is able to escape local authorites, then the child is then hunted down by the National Guard. If the National Guard cannot stop him/her, then we shall drop nuclear bombs around his area. Who cares how much forest it wipes out?
