When I signed up to volunteer at a local hospital last year, I didn't have any real expectations. I decided to do it mainly because my friends were planning to do volunteer work.
On my first day, I was told to stand next to an information sign to answer any question that came my way. On the third day, I noticed a wheelchair speeding in my direction. A young boy about six with the biggest smile I have ever seen was sitting in it. The boy stopped in front of me and said, "Who are you? You're in my hospital and I don't even know you!"
The boy with his irresistible（不可抗拒的） smile completely made me relax. I introduced myself and explained that I was new. Then, he began to tell me about his medical history, his favorite football player and other things about his life. From our conversation, I knew he was there for his weekly check-up. He wasn't afraid of being in hospital because he believed the doctor would cure（治愈） his legs at last. Our conversation changed my view of young children, illness and hospitals.
This led to my becoming a volunteer in the children's department and being a positive（积极的） person later, and also to my decision to study medicine at university and become a doctor. Volunteering might not do the same for everyone, but in my case, it was a life-changer.
