The air hostess was kept so busy that she forgot to give him the water. As a result, the passenger was held up to take his medicine. Thirty minutes later, when the passenger's ring for service sounded, she hurried over to him with a cup of water, but he refused.
In the following hours on the plane, each time the air hostess passed by the passenger, she would ask him with a smile whether he needed help or not. But the passenger never answered a word.
When he was going to get off the plane, the passenger asked the air hostess to hand him the passengers' booklet. She was very sad. She knew that he would write down sharp words, but with a smile she handed it to him.
Off the plane, she opened the booklet, and smiled, for the passenger put it. “On the flight, you asked me whether I needed help or not for twelve times in all. How can I refuse your twelve sincere smiles？”
That's right! Who can refuse twelve sincere smiles from a person？

Kindness or Strangers
At the store where I worked, I noticed a young boy of about ten shopping alone with his school list. He placed everything in his basket and went to the checkout.
The young shop assistant told him the total price, $37.60. the boy was instantly disappointed and said he had only been given $20. He took out one thing at a time until he got down to his $20. With eyes full of tears, he asked if he could phone his mum to pick him up. When he got through, it appeared that even this was inconvenient for his mother.
He bit hard on his lip to stop the tears and walked outside to wait on the bench in front of the shop. This was all too much for the young assistant who had served him and she said, “ I wish I could afford to pay for the rest of his things.” One of the other girls said she had a few dollars. Then two others said they could help as well.
These four young girls pooled their money and found that they had more than enough money for the boy’s extra purchases. So they upgraded his pens and pencils to top-quality ones, then took the bag out to the boy on the seat. His young face changed from sadness to the most beautiful smile. His mother arrived much later to pick him up. Instead of running to the car, he ran back into the store and called out, “ thank you!”
I was so proud of my team that day. They did something wonderful for that boy and also found the pleasure of giving was as great as receiving.
