One day，a man saw an old lady sitting inside her car at the side of the road.Though it was dark，he could see she needed help.So he stopped his car and walked towards her.The old lady was worried.Was he going to hurt her？ "I'll help you start your car，madam.By the way，my name is Bryan Anderson，"he said.
While Anderson was putting a spare tire （备胎） to her car，the lady began to talk to him.She thanked him much for coming to help.
Anderson just smiled as he put his tools away.The lady asked how much she should pay him.He told her that if she really wanted to pay him back，the next time she saw someone who needed help，she could give them the help they needed.He waited until she started her car and drove off.
A few miles down the road，the lady saw a small restaurant.She went in and a waitress came over with a sweet smile.The old lady noticed the waitress was nearly eight months pregnant（怀孕的），but she never let pains and aches change her smile when she served her.
The lady finished her meal and paid with a hundred﹣dollar bill.The waitress quickly went to get change，but the old lady was gone when the waitress came back.There was a note on the napkin （餐巾）， "You don't need to give me anything back.Somebody once helped me out the way I'm helping you.If you really want to pay me back，here is what you do—do not let this chain （链子） of love end with you." Under the napkin were four more 100 bills.
