Anna and I have been good friends when we were children. Two years ago, her family got into trouble because a terrible accident. To cheer her up, I always try my best to help her.

One day she said she would invite us to have lunch. I began to worry: she had no money, and if I offered to pay, I would hurt her. We arrived at a restaurant, where was small but seemed nice and quiet. She paid for only one meal and we were started to enjoy the delicious food together. She told me that the restaurant let people work for the meal if they had no money.

Life cannot be easy for us, but we can still do anything for our friends. The world will be nice if everybody would like to share happiness with others.
