My name is Penny. I started being a in a group called Kinds Camp in 1995. There were many kids in the camp. At that time. I was a street kid. I didn’t know what to do one of the workers asked if I wanted to help in the camp. I really didn’t know what to expect but I . The first day was for me. I thought the kids might not like and I was afraid to talk with them. But to my surprise, they were very and smiled(微笑) at me. By the end of that day, I found I working there. The kids didn’t if I wore old clothes or I couldn’t read well. They me for me the person not who my family were or how much money I had. Volunteering to help the disabled kids not only helped them but it helped me. It saved me from a road that might turn in the wrong direction. It me understand that no matter how bad your is there will always be someone else that has it much worse than you do. It gave me hope and made me find my place in the world. For that them greatly. Thank Kinds Camp for me a chance(机会) to volunteer. I will keep on volunteering.
