It's wrong for someone to lock up their child.
Rover's son Barker dropped a laptop and broke it, so Rover couldn't finish his project for work until the weekend.
Rover wants to teach Barker a lesson.
Rover takes away Barker's laptop and gives it back to him on Friday afternoon.
Rover locks Barker in his room with his dog Joe until Rover's work project is done.
Barker has to do homework all weekend and realizes that that's what he made his dad do.
Both Barker and Joe are starving by the time Rover lets them out and have learned nothing except not to tick off Rover.
