Volunteer work

Few days ago, my sister asked me whether I was free on this Sunday. She asked me whether I wanted to do volunteer work for the old folk home.
Since I wanted to upgrade myself spiritually, I told her that I was free.
On Sunday I followed my sister to the old folk home. Wow, I saw so many volunteer there. My sister and I helped out to peel off apples and packed bananas inside the box. Each box with 100 bananas to be distributed to elderly people in the old folk home.
This was the first time experiencing the volunteer work.
After few hours, the job was done, I felt joyful. I decided to do more volunteer work in the future.
Did you do the volunteer work before?
