One day, we had an important examination at school. I had prepared for it a lot. Before the examination, I accidentally found a boy who sat next to me didn't bring his pen. I thought the boy must have been very nervous and fearful, so I lent him a pen. He smiled at me thankfully. I was happy too.
I have helped many people. I hope you can help lots of people too!
