To be a volunteer is a great pleasure. Last Sunday, I get up early because I was so excited to sleep any longer. In morning, we arrived at the Happing Nursing Home. How happily the old people were when they saw us! Then we cleaned the windows or swept the floor for them, some of us gave some performances to them, such as sing songs and dancing. When it was time for us volunteers to leave, we were grateful for our kindness. From this meaningful activity, I have realized that we are supposing to care for the old. In our daily life, we should offer our seat to them on buses and treat our own grandparents more kindly. I sincerely hope more people will join in us.
