     I'm a volunteer for The American Diabetes (糖尿病) Association(ADA). I am on the planning committee

for a one-day cycling event called "Tour de Cure". It's sponsored by the ADA and the profits( 利润) of this

event are used for diabetes research and program funding.

     While I was talking to people about our "Tour de Cure" event in downtown Denver one day, I met a young

boy wearing a red hat from Oklahoma named Jack. I think he was 10-11 years old. It was the jar of red

rubber wrist bands (The American Diabetes Association diabetes awareness wrist bands) that caught Jack's

eye. These are the bands we give out to people who have diabetes, who have a family member who has

diabetes or to those people who know someone who has diabetes.

     People wear these for a variety of reasons: in memory of a loved one, to promote diabetes awareness and

to show support for people who have diabetes. Jack walked towards me eyeing the jar and then he said, "Can

I have one of those?" So, I replied to Jack, "Do you have someone in your family who has diabetes?" Jack

said,"No, but I know someone who has diabetes." So I gave him one to wear for his friend.

     Then, Jack began looking at our "Tour de Cure" photo album. When Jack had finished and was about to

go, he looked up at me and said,"Would you take a donation?" I was surprised to hear this from a

10-11-year-old boy, but I said, "Yes." I took the lid of our donation container off as Jack was reaching into

his pocket. His hand came out clinched around the donation he was about to make. It was my impression that

what he had in his hand was everything he had in his pocket, as he did not count it. After Jack dropped his

donation into the container, I gave him a high-five, as I so often do to acknowledge an accomplishment or

an appreciation. I also gave him a handshake before he parted. After Jack left, I counted his gift-$3.00. I then

realized that he gave all he had, without counting the cost.

     The heart of a child made me smile that day. Thank you, Jack.
