Dad , can I have a pet ? I did what you said and passed all of my exams .   Then I guess you get to have a pet . Do you know what you want ?   I want a dog . My friend Mindy's dog just had puppies and she said I can have one .   You know who will be responsible for feeding and cleaning and all of that stuff ?   I know , I know . I will do it all by myself .   Have you figured out the costs involved with feeding and caring for it ?   Yes . It will cost me about $ 50 a month . And I make a little more than that already .
