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
