In some of the stories, it might be that a child lies about their grades. They tell their parents they got all A's, but in reality, they got some C's. When the report card is about to come out, they are in a panic. They know that if their parents discover the truth, they'll be in big trouble and might get spanked. So they try all sorts of ways to either hide the report card or change the grades somehow.
One possible plot could be a child borrowing their parents' car without permission. They drive around the neighborhood, and maybe they accidentally scratch the car. Now they are really worried about getting spanked when their parents find out, so they keep it a secret and try to find a way to fix the scratch on their own.
