One day I went for a walk. There, I saw the fellow behind the tree. I went closer to make sure it was him. I thought, yes, this is the jacket it must be. He did not see me. I decided to scare him. quietly walked to the tree and covered his eyes. It turned out that it was not Johnny. I burned with shame. I do not know who it was.
