Power struggles, every parent has them but no one likes them.
You just asked your child to clean up their room and they respond with a ‘no’, so you tell them again, but their answer doesn’t change. This can keep going and it might end up in a power struggle between you and your child.
Why can’t they just do what you ask? Well, they want to control what they’re doing, and cleaning up their room isn’t a priority.
Children want to have some control about how they spend their time, they don’t like to be told what to do every minute of every day. But be honest, would you like this? I doubt it.
