One afternoon, while I was doing my homework, then suddenly I heard someone knocking at the door. I rose my head, looking out of the window to see who it was. A man of about 50 broad shoulders and glasses were standing on the door steps. He was tall, wearing in an old army coat. He grew a wild beard. A big black hat was pulling forward over his eyes so that it was hard to see her face clearly. His shoes were old but worn out. It was a big hole in one of his socks. He had with him a black box in one hand. Only after I took a few more closer looks at him I recognize that he was my neighbor ten years ago.
