Post: What shall I do?
Posted by a worried mother on 2 / May / 09 Anybody here?
      I have a 15-year-old daughter. She is lovely and clever. I love her very much.
But now she likes playing computer games very much. Once she gets home, she
does nothing but play computer games. No homework, no rest! When I talk to her,
she says nothing to me! When I turn off the computer, she will be very angry with
me! Oh! What shall I do?
