This afternoon I went to the bookstore near my house, only find it was closed. Just then, I noticed a schoolboy walking in front of me. When he passed by a white wall, he left two footprints on it. An old man, who saw that had happened, shouted at him angry. The boy felt afraid or ran away quickly.

    A few minutes later, another boys passed by the white wall and saw the footprints. He thought for a moment and took out of a pencil from his schoolbag. While I was wondered, I saw the boy painting the panda on the wall. And the footprints become the panda’s black eyes. What a smart boy I was!
