I found a website that has changed my life for the better. The website is wishuponahero.com and it is all about people helping others, not expecting anything in return.

I am a single mom with a son. My son’s 12th birthday was on October 29th, 2007. Knowing that I didn’t have money to buy him a birthday gift had broken my heart. So I decided to post a wish on wishuponahero.com for people to send my son birthday cards.

Many cards just started coming and my little son was very excited and this went on for about three weeks. The smile on his face and the sparkle (闪光) in his eyes brought me to tears.

Then, in the end of November, he started thinking about Christmas and he already knew that there would not be a tree for him because we didn’t have enough money. However, it didn’t matter to him. All he talked about was how much he wanted to make other children smile. So he decided that what he wanted to do was earn money to buy Christmas cards and send them to other children from poor families. My son went out daily and raked (耙) leaves and walked some dogs to make money. Not only did he buy cards, but he also made enough money to buy all the stamps and lollipops (棒棒糖) to be sent with the cards. He sent out about 100 cards. Doing this brought him that same smile and sparkle in his eyes as did the birthday cards that he received.
