Yesterday, I picked up a schoolbag in the school library. It was a blue and black schoolbag with a cartoon pattern on it. When I opened it, I found some textbooks, a notebook and a pencil case. The textbooks had the name "Jack" written on them. I guessed it must belong to Jack, who is my classmate and loves blue. He always takes a lot of books with him.
I asked some classmates if they knew where Jack was. Finally, I found him in the classroom. I returned the schoolbag to him. He was very happy and thanked me. I felt really good that I could help him.
