My Volunteer Experience
I am a 14-year-old student and I have been a volunteer in the local old people's home for one year. I first went there in last summer vacation, and I have never missed a weekend since then.
The old people there are very lonely, so I often go to talk with them and read newspapers for them. I have told them many interesting stories these months, and they have shared their life experiences with me since I met them. Some of them have not left the old people's home for a long time, so I also help them take a walk in the garden.
My best friend Lucy has joined me in the volunteer work since last September. She is good at singing and she has sung many old songs for the elderly for four months. The old people always clap their hands and smile when they listen to her songs. We have made many friends with the elderly since we started the volunteer work, and we feel very happy to help them.
Volunteering has changed me a lot this year. I have learned to care about others and be thankful for my life. I know I will keep doing volunteer work in the future, because giving is better than receiving.
