The last one isn't a paradox. He's a kid, his parents could have forced him to go to bed, doesn't mean he is actually tired.
Even as an adult you could convince yourself you need to go to bed since you need to get up early, doesn't mean you are actually tired
Another bedtime paradox. If a man commits suicide and a wife commits to killing whoever killed him, then she found out he committed suicide, who does she kill?
Even as an adult you could convince yourself you need to go to bed since you need to get up early, doesn't mean you are actually tired
Those are not sentences.
