One afternoon, I was doing my homework, suddenly I heard someone knocking at
the door. I rose my head, looking out of the window to see who it was. The man of
about 50 with 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 his face clear. His shoes were old and
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 look at him I recognize that he used to be
my neighbor ten years age.
