One day, my mother was busy cooking dinner. She asked me to buy some tomatoes because she was short of tomatoes and she couldn't walk now. This is my first time to go to the market. At first, I didn't know which store to choose. I was a little afraid to face so many people. Then I remembered my mother and did as she did. Finally, I bought tomatoes. I was very happy.
