Last year, I worked in a middle school near my1 house, and I stayed with her for a month. During that time, I helped her do some housework and2 some food.
After the first week, I noticed that the food was eaten up very3. Then I began keeping a(n)4 on my mum. To my surprise, I found that she would put some of the food into a paper5 and go out with it at about nine every morning. And finally, I decided to6her. I saw her taking the food to the street7. She would also spend a lot of time talking and playing with them.
One day, I talked to a neighbor and8 that my mum was popular in the area. The children were very friendly to her and even thought of her as their own9. Then it hit me; why wouldn't she want to tell me about it? Was she10 that I would stop buying food if I found out?
11 my mum got home, I gave her a big hug (拥抱). I told her she didn't need to keep it12 from me. And she told me something about the children. Some of13 lived with an old lady in a small house,14 slept on the street. For years, she was helping the poor street children by giving them food. After she told me everything, I was so moved by how selfless (无私的) she was. She helped people need. As her son, I was so15 my mum.
But I always added one more bag for her other children.
