Article: He was driving home one evening, on a country road. Work, in this small community, was as slow as his broken Pontiac. But he never quit looking. Since the factory closed, he'd been unemployed. And with winter approaching, the cold days had finally hit home. It was a lonely road. Very few people had a reason to be on it, unless they were leaving. Most of his friends had left. But he stayed on. After all, he had his root here. It was getting dark, and snow was coming down. He'd better get a move on. Suddenly he saw an old lady on the roadside and obviously needed help. So he pulled up in front of her Mercedes and got out. She was worried. No one had stopped to help for the last hour or so. Was he going to hurt her? He looked poor, hungry, and ... dangerous. He could see that she was frightened, standing out there in the cold. He said, "I'm here to help you, Ma'am. Why don't you wait in the car where it's warm? By the way, my name is Joe." The car had a flat tire. Joe crawled under the car and soon he was able to change the tire. But he had to get dirty and his hands hurt. As he was turning the screws ,she rolled down her window and began talking to him and said she couldn't thank him enough for coming to her aid. She asked him how much she owed him. Any amount would have been alright with her. She had already imagined all the terrible things that could have happened had he not stopped. Joe never thought twice about the money. This was simply helping someone in need, and God knows there were plenty who had lent him a hand before. He had lived his whole life that way, and it never occurred to him to act any other way. He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she could give that person the assistance they needed, and Joe added "... and think of me." A few miles down the road the lady saw a small cafe. She went in to grab a bite to eat, and take the chill off. It was a dirty-looking restaurant. Outside were two old gas pumps. The whole scene was unfamiliar to her. The waitress came over and brought a clean towel to wipe her wet hair. She had a sweet smile, one that even being on her feet for the whole day couldn't erase. The lady noticed that the waitress was nearly eight months pregnant, but she never let the strain and aches change her attitude. The old lady wondered how someone who had so little could be so giving to a stranger. Then she remembered Joe. After the lady finished her meal, she handed the waitress a $100 bill. When the waitress came back with the change, she found the lady was gone and something written on a napkin. Reading the note, there were tears in her eyes. It said, "You owe me nothing. I've been there too. Someone once helped me out, like I'm helping you. If you really want to pay me back, don't let the chain of love end with you. That night when she got home from work, she was thinking about the money and what the lady had written. With the baby due soon, life would be harder. She knew how worried her husband was, and as he lay sleeping next to her, she gave him a soft kiss and whispered soft, "Everything's gonna be alright; I love you, Joe."

Article: Personal money-management website Mint.com suggests recently that responsible parents should give their kids credit cards--possibly starting as young as middle school. The website says a credit card will help children master responsible spending habits and give parents the chance to teach them some valuable lessons. It's absolutely true that kids should learn about how a credit card works and how to use it responsibly. But the idea that they need a card of their own to practise this is questionable. Yes, credit cards are a teaching tool, but it's the time you spend educating them about money management that does the teaching, not the piece of plastic. Sit down with your child--here we are referring to teens and walk them through your credit card statements. Point out important things like the due date, late fee warning, and APR . If you have good credit, adding a child as an authorized user onto one of your credit cards also provides teachable moments. Allow kids to use the card to make specific purchases and require their participation in payment. Since the card is still in your name, you can take them off it at any point and cut off their access if they're not able to handle the responsibility. Another option is to set them up with an account at a local bank that offers free use of a debit card . Unlike credit card, the debit card has no overdraft function. Children can only use the card to pay for things and the money is taken directly from their bank account. If the account is empty, the worst that will happen is the card being declined at a cash register.
Question: Why does Mint.com advise parents to give middle school kids credit cards?
Options: (A) To leave their kids financially independent. (B) To help their kids form good spending habits. (C) To teach their kids' how to save pocket money. (D) To strengthen the relationship with their kids.
