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.

The other day after work, I was walking down the street while I saw a boy riding a unicycle, one of those bicycle with only one wheel. Dressing in all pink from head to toe, he was singing a song which was sounded like a kid’s song. I thought he must be total crazy. Just then, a lady dropped 20-dollar bill on the ground, but he didn’t realize it and started to walk away. The guy in pink picked out the money and gave it back to her. After that, he rode on but soon disappeared before the lady could thank him. How a strange and good guy!.
