Dear Sir,
I’m a middle school student. I am willing be a volunteer to help others. Although I am busy I still wanted to visit Old People’s Home as a volunteer. Apart from do some cleaning for the old people, giving some performance with my friends are another thing I can do. I believe I’ll be the person who can get on good with the old there.
Besides, I am ready to give a hand to sick children in hospital. I love children but I’ll devote myself to taking good care of him. In a word, I would like to help those people whom need help.
Please get in touch with me by phone or by the mail.
Warm-hearted
Jim
