Last week, when I went home after school, I went to a shop to buy something to drink. Then when I went out of the shop, I found my book was lost. I felt so worried and went back to the shop. The shop assistant helped me to search. Finally, she found the book in the corner. I felt so thankful to her. She was such a nice girl.
