When I got downstairs, I took out a chestnut, peeled off the shell, put the pulp into my mouth, and threw the chestnut shell casually in the yard of the community. Just as I was savoring the deliciousness of chestnuts, a footsteps sounded behind me, followed by the sound of "swish, swish, swish". I didn't care too much and still happily ate chestnuts while walking.

After a while, I found that this mysterious footsteps were still following me. I started to get a little scared. Is someone following me? Who is it? At this time, my heart was full of questions. Finally, I reached the duty room. I slowed down and looked back quietly, but I didn't see anything.

After stopping for a while, I continued walking forward, and the footsteps sounded again. My heart became nervous again, could it be a ghost? Although I don't believe that there are real ghosts in the world, I am still a little scared. I quietly looked behind me, and the scene surprised me. It turned out that a diligent cleaner was following me all the way to clean the chestnut shells I threw away. Suddenly, my face turned red. I quickly picked up the chestnut shell I had just thrown away, threw it into the trash can, and ran away as fast as I could.

I looked back again, and the cleaner smiled at me while wiping the sweat from his forehead. I will never forget that smile. It was that smile that told me to be a good child who corrects his mistakes when he knows they are wrong, but also to be a civilized person who knows how to respect the work of others.
