Last Tuesday, after doing all the family shopping in town, I wanted to have a rest before catching the train. So I bought a newspaper and some chocolate and went into a station coffee shop with long tables to sit at. I put my heavy bag down on the floor, put the newspaper and chocolate on the table to keep a place, and went to get a cup of coffee.
When I came back with my coffee, there was someone sitting near to me. It was one of those strange-looking young men, with dark glasses, torn clothes, and long hair. But I wasn't surprised at such a young man. What surprised me most was that he had started to eat my chocolate!
I was rather uneasy about him, but I didn't want to get into trouble. I just looked down at the front page of the newspaper and took a bit of chocolate. The boy looked at me. Then he took a second piece of my chocolate. I could hardly believe it. Still I didn't say anything. When he took a third one, I felt  more angry than uneasy. I thought, "Well, I shall have the last piece." And I got it.
The boy gave me a strange look and then stood up. As he left, he shouted out, "This woman is crazy!" Everyone looked at me. That was embarrassing（令人难堪） enough. But it was worse when I finished my coffee and ready to leave. It wasn't my chocolate I had eaten a moment before. Mine was just under my newspaper.
