A、Linda enjoys doing a part-time job because it brings her a lot of money. B、Linda spends so much time on her part-time job that

Man: I really enjoyed coming to your store, Linda. It was interesting seeing you at work. You’re very professional.
   Woman: Thanks, Wang. I’ve been working here since I was sixteen, so I’ve learned a lot.
   Man: I just don’t understand why you work. In China, children who are in school never work. Besides, your parents make plenty of money.
   Woman: Sure, Mom and Dad could give me everything I need, but they think it’s good for me to learn some responsibility, how to plan a budget, and what I should pay for out of my salary. I’ve been working almost three years now. I’m getting much better at handling money.
   Man: Do you give your money to your parents, or do you pay rent and buy groceries?
   Woman: No, what I earn is mine. Mom and Dad pay for all the serious stuff. I pay for some of my clothes and school supplies, but mostly I pay for my entertainment. That way I can learn how to spend it wisely.
   Man: Do your parents give you advice on how to spend your money?
   Woman: Yeah, when I planned my budget, Dad said I should save about half of what I earn so that I can pay for some of my college. He says if I pay for it, I’ll probably study harder and appreciate it more.  And I am saving money for college. I have a scholarship for my tuition, but buy my own textbooks and pay for some of the extras like skiing class.
   Man: But doesn’t working interfere with your studies?
   Woman: I had a little trouble at first because I was used to having a lot of free time, but I learned to be organized. I do a lot of studying at school between classes, and I get up really early. I’ve learned to fit everything in. In fact, I’ve been getting better grades since I started working.
   Man: You’ve almost convinced me, and this seems to go along with your general philosophy of independence.
