Dear Molly, I know how you feel. People always tell us, “Don’t do this!” or “You can’t do that!” But think about it, Molly. There 1 a lot of things you can do. You can play basketball 2 weekends. You can watch TV after you 3 a book. Parents and schools are sometimes strict, 4 remember, they make rules to help us. We have 5 them. Good luck! Dr. Know
